Let X₁, X₂, X₃, ... be i.i.d. variables taking values between +1 and +[infinity] with probability density given by:
f(x) = (λ - 1)/x^λ
for every x ≥ 1 where λ > 1 is an unknown parameter. For x < 1, we assume the probability density to be 0. Estimate λ using maximum likelihood, given X₁ = 3, X₂ = 4, X₃ = 5
Answers
To estimate the unknown parameter λ using maximum likelihood, given X₁ = 3, X₂ = 4, X₃ = 5, we need to find the value of λ that maximizes the likelihood function based on the observed data. The likelihood function represents the probability of observing the given data for different values of λ.
The likelihood function L(λ) is defined as the product of the probability density function evaluated at each observed data point. In this case, we have L(λ) = f(3) * f(4) * f(5), where f(x) is the given probability density function.
Substituting the values into the likelihood function, we have L(λ) = ((λ - 1)/3^λ) * ((λ - 1)/4^λ) * ((λ - 1)/5^λ).
To find the maximum likelihood estimate of λ, we need to maximize the likelihood function. Taking the natural logarithm of the likelihood function (ln L(λ)), we can simplify the problem to finding the value of λ that maximizes ln L(λ).
Taking the derivative of ln L(λ) with respect to λ and setting it to zero, we can solve for the maximum likelihood estimate of λ.
By solving the equation, we can obtain the estimate for λ based on the observed data X₁ = 3, X₂ = 4, X₃ = 5.

No two watermelons have the same measured weight. b) watermelon x is related to watermelon y if the measured weight of watermelon x is at least the measured weight of watermelon y. All watermelons have exactly the same measured weight
Answers
a) The relation is reflexive, symmetric, and transitive.
b) The relation is not reflexive, symmetric, or transitive.
a) For each watermelon x, x is related to x because the measured weight of x is at least the measured weight of x. Therefore, the relation is reflexive.
For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is also related to x (meaning the measured weight of y is at least the measured weight of x). Therefore, the relation is symmetric.
For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is related to z (meaning the measured weight of x is at least the measured weight of z). Therefore, the relation is transitive.
b) For each watermelon x, x is not related to x because no two watermelons have the same measured weight. Therefore, the relation is not reflexive.
For each watermelon x and y, if x is related to y (meaning the measured weight of x is at least the measured weight of y), then y is not related to x (meaning the measured weight of y is not at least the measured weight of x).
Therefore, the relation is not symmetric. For each watermelon x, y, and z, if x is related to y (meaning the measured weight of x is at least the measured weight of y) and y is related to z (meaning the measured weight of y is at least the measured weight of z), then x is not related to z (meaning the measured weight of x is not at least the measured weight of z).
Therefore, the relation is not transitive.

Answers
Answer:
0.004 km; 400 cm; 4000 mm
Step-by-step explanation:
1 km = 1000 m
1 = (1 km)/(1000 m)
4 m * (1 km)/(1000 m) = 4/1000 km = 0.004 km
1 m = 100 cm
1 = (100 cm)/(1 m)
4 m * (100 cm)/(1 m) = 400 cm
1 m = 1000 mm
1 = (1000 mm)/(1 m)
4 m * (1000 mm)/(1 m) = 4000 mm
Answer: 0.004 km; 400 cm; 4000 mm

Under 30 30 - 50 Over 50 Yes 35 64 25 56 19 1 No A test is conducted at the a = 0.100 significance level to determine whether age and voting behavior are independent Fill in the expected"table for this independence test. Age Voted? Under 30 30 - 50 Over 50 Yes 88 No Find the value of the chi-square statistic for this independence test.
Answers
The value of the chi-square statistic for this independence test is approximately 82.23.
To calculate the expected values for the independence test, we need to determine the expected number of individuals in each category if age and voting behavior were independent. We can calculate the expected values using the formula:
Expected value = (Row total * Column total) / Total number of observations
Let's calculate the expected values for each category:
Age Voted? Under 30 30 - 50 Over 50 Total
Yes 35 64 25 124
No 56 19 1 76
Total 91 83 26 200
Expected value for "Yes" under "Under 30" category:
Expected value = (91 * 124) / 200 = 56.57 (approximately 57)
Expected value for "No" under "Under 30" category:
Expected value = (91 * 76) / 200 = 34.82 (approximately 35)
Similarly, calculate the expected values for the other categories:
Expected values for "Yes" in the "30 - 50" and "Over 50" categories:
30 - 50: 83 * 124 / 200 ≈ 51.77 (approximately 52)
Over 50: 26 * 124 / 200 ≈ 16.12 (approximately 16)
Expected values for "No" in the "30 - 50" and "Over 50" categories:
30 - 50: 83 * 76 / 200 ≈ 31.63 (approximately 32)
Over 50: 26 * 76 / 200 ≈ 9.88 (approximately 10)
The expected table for the independence test is as follows:
Age Voted? Under 30 30 - 50 Over 50 Total
Yes 57 52 16 124
No 35 32 10 76
Total 91 83 26 200
To find the chi-square statistic for this independence test, we use the formula:
χ² = Σ [(Observed value - Expected value)² / Expected value]
Now, let's calculate the chi-square statistic by summing the values for each category:
χ² = [(35 - 57)² / 57] + [(64 - 52)² / 52] + [(25 - 16)² / 16] + [(56 - 35)² / 35] + [(19 - 32)² / 32] + [(1 - 10)² / 10]
χ² = 23.09 + 2.46 + 5.06 + 40.69 + 4.53 + 6.4
χ² ≈ 82.23
Therefore, the value of the chi-square statistic for this independence test is approximately 82.23.

Answers
Answer:
Answer:
68%
Step-by-step explanation:
The percentage of males in the town who have systolic blood pressure between 98 and 112 is 68%.
What is a normal distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 7.
68 percent of the data is within one standard deviation of the mean, i.e. between μ - σ and μ + σ.

Answers
The relationship between the variables x and y, based on the given data points, can be represented by the equation y = -3.30x + 9.77.
This linear equation captures the trend observed in the data, providing a mathematical expression to estimate the value of y corresponding to a given x. By performing linear regression on the provided data points, the equation y = -3.30x + 9.77 is derived. This equation represents a linear relationship between x and y, where the coefficient of x is -3.30, indicating that as x increases, y decreases at a rate of 3.30 units.
The constant term 9.77 represents the y-intercept, which is the value of y when x is 0. This equation serves as a model to estimate the value of y for any given x within the observed range. It provides a straightforward and concise representation of the relationship between the variables based on the given data.

Brand X sells 21 oz. bags of mixed nuts that contain 29% peanuts. To make their product they combine Brand A mixed nuts which contain 35% peanuts and Brand B mixed nuts which contain 25% peanuts. How much of each do they need to use? Show all work.
explain your steps and answer clearly
Answers
Brand X needs to use 8.4 oz. of Brand A mixed nuts and 12.6 oz. of Brand B mixed nuts to achieve a 29% peanut content in their 21 oz. bags of mixed nuts.
To determine how much of Brand A and Brand B mixed nuts Brand X needs to use to achieve a 29% peanut content in their 21 oz. bags of mixed nuts, we can set up an equation based on the principle of weighted averages.
Let's assume x represents the amount of Brand A mixed nuts (35% peanuts) that Brand X needs to use, and y represents the amount of Brand B mixed nuts (25% peanuts) that Brand X needs to use.
The total weight of the mixed nuts is given as 21 oz., so we can set up the following equation:
x + y = 21 (Equation 1)
To achieve a 29% peanut content in the final product, we can set up another equation based on the peanut content:
(35% of x) + (25% of y) = 29% of 21 oz.
0.35x + 0.25y = 0.29 * 21 (Equation 2)
Now we have a system of two equations (Equation 1 and Equation 2). We can solve this system of equations to find the values of x and y.
Let's solve the system using the substitution method:
From Equation 1, we have: x = 21 - y
Substituting this into Equation 2, we get:
0.35(21 - y) + 0.25y = 0.29 × 21
7.35 - 0.35y + 0.25y = 6.09
0.1y = 6.09 - 7.35
0.1y = -1.26
y = -1.26 / 0.1
y = 12.6
Substituting this value back into Equation 1, we can find x:
x + 12.6 = 21
x = 21 - 12.6
x = 8.4
Therefore, Brand X needs to use 8.4 oz. of Brand A mixed nuts and 12.6 oz. of Brand B mixed nuts to achieve a 29% peanut content in their 21 oz. bags of mixed nuts.
for such more question on weighted averages.

Use cylindrical coordinates to evaluate
∫∫∫ xyzdv
where E is the solid in the first octant that lies under the paraboloid. z= 4-z² - y².
Answers
To evaluate the triple integral ∫∫∫ xyzdv using cylindrical coordinates, we need to express the integral in terms of the cylindrical coordinates (ρ, φ, z).
The given solid E lies under the paraboloid z = 4 - z² - y². In cylindrical coordinates, this paraboloid equation becomes z = 4 - ρ² - y².
To set up the triple integral, we need to determine the limits of integration for each variable.
Since the solid lies in the first octant, the limits of integration are as follows:
ρ: from 0 to some value ρ₁
φ: from 0 to π/2
z: from 0 to the upper limit of the paraboloid, which is given by the equation z = 4 - ρ² - y².
Now we can set up the triple integral:
∫∫∫ xyzdv = ∫₀^(π/2) ∫₀^ρ₁ ∫₀^(4-ρ²-y²) (ρcosφ)(ρsinφ)z dz dρ dφ
Simplifying the integrand and integrating, we can evaluate the triple integral to obtain the final result.
Note: The specific value of ρ₁ and the complexity of the integration depend on the precise shape of the solid E, which is not provided in the given information. Therefore, the final evaluation of the integral requires additional information about the solid E.

What is the probability of 2 people not sharing the same birthday out of 365?
Answers
There is a 99.73% chance that two people selected at random will not share the same birthday out of 365.
The probability of two people not sharing the same birthday out of 365 can be calculated using the formula:P(A) = n(A)/n(S)where n(A) is the number of favorable outcomes and n(S) is the total number of possible outcomes.
In this case, the favorable outcome is that two people do not share the same birthday, and the total number of possible outcomes is 365 × 365 since each person can have a birthday on any of the 365 days.
To find the number of favorable outcomes, we need to subtract the number of ways two people can have the same birthday from the total number of possible outcomes.
The number of ways two people can have the same birthday is simply 365 since there are 365 possible birthdays.
Therefore, the number of favorable outcomes is:365 × 364
The total number of possible outcomes is:
365 × 365
Thus,the probability of two people not sharing the same birthday out of 365 is:P(A) = (365 × 364)/(365 × 365)P(A) ≈ 0.9973
