For a new study conducted by a fitness magazine, 260 females were randomly selected. For each, the mean daily calorie consumption was calculated for a September-February period. A second sample of 300 females was chosen independently of the first. For each of them, the mean daily calorie consumption was calculated for a March-August period. During the September-February period, participants consumed a mean of 2387.1 calories daily with a standard deviation of 210. During the March-August period, participants consumed a mean of 2412.9 calories daily with a standard deviation of 267.5. The population standard deviations of daily calories consumed for females in the two periods can be estimated using the sample standard deviations, as the samples that were used to compute them were quite large. Construct a 90% confidence interval for μ1−μ2, the difference between the mean daily calorie consumption of μ1 females in September-February and the mean daily calorie consumption of μ2 females in March-August.
Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.)
What is the lower limit of the 90% confidence interval?
What is the upper limit of the 90% confidence interval?

Answers

Answer 1

the lower limit of the 90% confidence interval is approximately -65.25, and the upper limit is approximately 13.65.

To construct a 90% confidence interval for the difference between the mean daily calorie consumption of females in September-February (μ₁) and the mean daily calorie consumption of females in March-August (μ₂), we can use the formula:

CI = ([tex]\bar{X_1}[/tex] - [tex]\bar{X_2}[/tex]) ± Z * √((s₁² / n₁) + (s₂² / n₂))

Where:

[tex]\bar{X_1}[/tex] and [tex]\bar{X_2}[/tex] are the sample means of calorie consumption for the two periods.

s₁ and s₂ are the sample standard deviations of calorie consumption for the two periods.

n₁ and n₂ are the sample sizes for the two periods.

Z is the z-score corresponding to the desired confidence level.

Given data:

[tex]\bar{X_1}[/tex] = 2387.1 (mean daily calorie consumption for September-February)

[tex]\bar{X_2}[/tex] = 2412.9 (mean daily calorie consumption for March-August)

s₁ = 210 (standard deviation for September-February)

s₂ = 267.5 (standard deviation for March-August)

n₁ = 260 (sample size for September-February)

n₂ = 300 (sample size for March-August)

Confidence level = 90%

First, we need to find the z-score corresponding to a 90% confidence level. The z-score can be found using a z-table or a calculator. For a 90% confidence level, the z-score is approximately 1.645.

Now, we can substitute the values into the formula to calculate the confidence interval:

CI = (2387.1 - 2412.9) ± 1.645 * √((210² / 260) + (267.5² / 300))

Calculating the values inside the square root:

√((210² / 260) + (267.5² / 300)) ≈ √(342.461538 + 238.083333) ≈ √(580.544872) ≈ 24.107

Substituting the values into the formula:

CI = -25.8 ± 1.645 * 24.107

Calculating the limits of the confidence interval:

Lower limit = -25.8 - 1.645 * 24.107 ≈ -65.246

Upper limit = -25.8 + 1.645 * 24.107 ≈ 13.646

Rounding the values to two decimal places:

Lower limit ≈ -65.25

Upper limit ≈ 13.65

Therefore, the lower limit of the 90% confidence interval is approximately -65.25, and the upper limit is approximately 13.65.

A small internet trading company estimates that each network blackout results in a $500 loss. Compute expectation and variance of this company’s daily loss due to blackouts.
x = 0, 1, 2
Px = 0.7, 0.2, 0.1

Answers

The expectation (mean) of the company's daily loss due to blackouts is $200, and the variance is $350.

To compute the expectation of the company's daily loss, we multiply each possible loss value by its corresponding probability and sum them up. In this case, we have three possible loss values (0, 1, and 2) with their respective probabilities (0.7, 0.2, and 0.1). Multiplying each loss value by its probability and summing them gives us the expected value of $200.

To calculate the variance, we need to find the squared differences between each possible loss value and the expected value, multiply them by their respective probabilities, and sum them up. Squaring the differences ensures that negative differences do not cancel out positive differences. In this case, the variance is calculated as (0 - 200)^2 * 0.7 + (1 - 200)^2 * 0.2 + (2 - 200)^2 * 0.1, resulting in a variance of $350.

The expectation and variance provide useful measures of the central tendency and variability, respectively, of the company's daily loss due to blackouts.

Trigonometric identity is cosine. And a is 32.965327740597°.

What are the trigonometric identities?

Equations using trigonometric functions that hold true for all possible values of the variables are known as trigonometric identities.

Given:

A triangle with an adjacent leg to hypotenuse ratio value of 0.839.

Assume the triangle is a right-angled triangle.

In the right-angled triangle,

the ratio of adjacent leg to hypotenuse is cosine.

So,

Cos(a) = Adjacent leg/Hypotenuse

Cos(a) = 0.839

a = Cos⁻¹(0.839)

a = 32.965327740597°

Therefore, angle measure of a is 32.965327740597°.

Find the charge on the capacitor in an LRC-series circuit at t = 0.03 s when L = 0.05 h, R = 3.12, C = 0.008 f, E(t) = 0 V, 9(0) = 4 C, and i(0) = 0 A. (Round your answer to four decimal places.) 0.8630 хс Determine the first time at which the charge on the capacitor is equal to zero. (Round your answer to four decimal places).

Answers

At t = 0.03 s, the charge on the capacitor in the LRC-series circuit is 0.8630 C.

In an LRC-series circuit, the charge on the capacitor can be calculated using the formula Q(t) = Q(0) * e^(-t/(RC)), where Q(t) is the charge at time t, Q(0) is the initial charge on the capacitor, R is the resistance, C is the capacitance, and e is the base of the natural logarithm.

Given the values L = 0.05 H, R = 3.12 Ω, C = 0.008 F, E(t) = 0 V, Q(0) = 4 C, and i(0) = 0 A, we can substitute these values into the formula. Using the given time t = 0.03 s, we can calculate the charge on the capacitor.

Plugging in the values, we have Q(0.03) = 4 * e^(-0.03/(3.12*0.008)). Evaluating this expression gives us Q(0.03) ≈ 0.8630 C, rounded to four decimal places.

The test statistic of z = 2.58 is obtained when testing the claim that p = 0.85. Find the P-value. (Round the answer to 4 decimal places and enter numerical values in the cell)

Answers

Given z-score is z = 2.58 and the null hypothesis isH0: p = 0.85, where p is the true proportion, and we need to find the p-value.

We know that for a two-tailed test, the p-value is the probability that a z-score is greater than or equal to the absolute value of the calculated z-score or less than or equal to its negative value. So, the p-value for a two-tailed test is: p-value = P(z ≥ 2.58) + P(z ≤ -2.58)  ..............(1) Here, z = 2.58 represents the upper critical value, and the negative of it is the lower critical value (z = -2.58)

As the given hypothesis is a two-tailed test, we need to calculate the probabilities for both critical values. From the standard normal distribution table, the probabilities for these critical values are:

P(z ≥ 2.58) = 0.0049 (approx.)  P(z ≤ -2.58) = 0.0049 (approx.)

Substituting these values in equation (1), we get: p- value = 0.0049 + 0.0049 p-value = 0.0098Hence, the p-value is 0.0098 (approx.)

You believe that a corporation's dividends will grow 5% on average into the foreseeable future. If the company's last dividend payment was $5 what should be the current price of the stock assuming a 12% required return?

Answers

The calculated value of the current price of the stock is $75

How to calculate the current price of the stock

From the question, we have the following parameters that can be used in our computation:

Growth = 5%

Required return = 12%

Last dividend payment = $5

The dividend is calculated as

D = Last dividend payment * (1 + Growth )

So, we have

D = 5 * (1 + 5%)

Evaluate

D = 5.25

the current price of the stock is calculated as

Price = D/(r - g)

So, we have

Price = 5.25/(12% - 5%)

Evaluate

Price = 75

Hence, the current price of the stock is $75

His demand is pretty steady throughout the year (his website is up and running 365 days a year), approximately normally distributed with a mean of 30 T-shirts/day and a standard deviation of 10 T-shirts/day. He has a supplier in China that charges him $5 per T-shirt T and a flat rate of $150 every time he places an order. Orders take exactly 50 days to arrive by container ship. His calculates his annual per unit holding costs at 20% of the wholesale cost of T-shirts. a) What type of inventory management problem is this? Explain your answer. i) Newsvendor (single period) model ii) EOQ model with continuous demand distribution 111) EOQ model with discrete demand distribution b) Calculate how many T-shirts he should order from his China supplier at a time. c) Calculate the level at which he should reorder T-shirts from China to experience at most a 10% chance of a stocking out. a T-shirts, Juan should place an order for d) Fill in: When inventory drops to more T-shirts.

Answers

Juan should order approximately 1,813 T-shirts from his China supplier at a time.

How to explain the information

This inventory management problem can be categorized as the EOQ (Economic Order Quantity) model with continuous demand distribution. In this case, the demand for T-shirts is approximately normally distributed, and the EOQ model assumes a continuous demand pattern.

In order to calculate the optimal order quantity (EOQ), we can use the following formula:

EOQ = ✓((2 * D * S) / H)

where:

D = Annual demand (mean) = 30 T-shirts/day * 365 days/year = 10,950 T-shirts/year

S = Ordering cost per order = $150

H = Holding cost per unit = 20% of wholesale cost = 0.2 * $5 = $1

EOQ = ✓((2 * 10,950 * 150) / 1)

= ✓(3,285,000)

≈ 1,812.99

Therefore, Juan should order approximately 1,813 T-shirts from his China supplier at a time.

Answers

The probability of selecting a value at random and discovering that it has a value of less than 395 pounds is 0.3085.

a. The area between 415 pounds and a mean of 400 pounds is:

0.9332 - 0.5 = 0.4332.

b. The area between the mean and 395 pounds is:

0.5 - 0.3085 = 0.1915

c.The probability of selecting a value at random and discovering that it has a value of less than 395 pounds is 0.3085.

Given the mean of a normal probability distribution as 400 pounds and the standard deviation as 10 pounds.

We have to calculate the area between 415 pounds and a mean of 400 pounds, the area between the mean and 395 pounds, and the probability of selecting a value at random and discovering that it has a value of less than 395 pounds.

a. What is the area between 415 pounds and a mean of 400 pounds?

The Z-score can be calculated as follows:

Z = (x - μ) / σ

= (415 - 400) / 10

= 1.5

From the Z-table, the area to the left of 1.5 is 0.9332.

Therefore, the area between 415 pounds and a mean of 400 pounds is:

0.9332 - 0.5 = 0.4332.

b. What is the area between the mean and 395 pounds?

The Z-score can be calculated as follows:

Z = (x - μ) / σ

= (395 - 400) / 10

= -0.5

From the Z-table, the area to the left of -0.5 is 0.3085.

Therefore, the area between the mean and 395 pounds is:

0.5 - 0.3085 = 0.1915.

c. What is the probability of selecting a value at random and discovering that it has a value of less than 395 pounds?

The Z-score can be calculated as follows:

Z = (x - μ) / σ

= (395 - 400) / 10

= -0.5

From the Z-table, the area to the left of -0.5 is 0.3085.

They incur the following expenses related to construction of the asset through 2015: Date Amount 2/28/2015 $1,200,000 4/30/2015 $2,100,000 6/30/2015 $1,000,000 8/31/2015 $3,000,000 12/31/2015 $2,000,000 The company had the following debt outstanding at December 31, 2015: 1.) $3,000,000, 10%, 5-year note specifically borrowed to finance construction of equipment dated January 1, 2015, with interest payable annually on December 31 2.) $5,000,000, 12%, ten-year bonds issued at par on December 31, 2009, with interest payable annually on December 31 3.) $2,500,000, 9%, 3-year note payable, dated January 1, 2014, with interest payable annually on December 31 Compute Avoidable Interest: The well-known psychologist Dr. Elbod has established what he calls his Generalized Anxiety Scale (GAS). The GAS, which is a scale from 0 to 10, measures the "general anxiety" of an individual, with higher GAS scores corresponding to more anxiety. (Dr. Elbod's assessment of anxiety is based on a variety of measurements, both physiological and psychological.) The bivariate data below give the GAS score (denoted by x) and the number of hours of sleep last night (denoted by y) for each of the fifteen adults in a study. The least-squares regression line for these data has equation y = 8.42 -0.27%. This line, along with a scatter plot of the sample data, is shown below. GAS score, X Sleep time, y (in hours) 5.0 5.8 3.2 7.1 6.6 6.3 10+ 1.0 7.4 8.1 6.6 9+ X X 2.0 X 8.1 6.6 9.0 X Sleep time (in hours) 7 X x 6.0 8.1 X X X X 1.5 8.6 6 4.1 6,8 5 3.4 7.6 5.6 U 10 8.0 8.8 5.4 GAS score 6.6 7.1 3.7 8.7 Based on the study's data and the regression line, complete the following. s ? (a) For these data, GAS scores that are less than the mean of the GAS scores tend to be paired with sleep times that are (Choose one) the mean of the sleep times. (b) According to the regression equation, for an increase of one in GAS score, there is a corresponding decrease of how many hours in sleep time?
