Steven measures the weight of a random sample of 49 basset hounds the mean wait was 45.8 lb with a standard deviation of 3 lb using the alternative hypothesis that Miu is less than 45.8 Steven found a ztest statistic of -1.5 what is the p value of the test statistic​

Answers

Answer 1

Answer: 0.067

Step-by-step explanation:

Look at chart, go to the row for the z-column for -1.5 and then the column 0, this value is 0.0668 or 0.067.

Answer 2

The p-value of the test statistic is approximately 0.0668.

Given that,

Steven measured the weight of a random sample of 49 basset hounds.

The mean weight of the sample was 45.8 lbs.

The standard deviation of the sample was 3 lbs.

Steven used an alternative hypothesis that the true mean weight is less than 45.8 lbs.

Steven found the z-test statistic of -1.5.

Based on the information provided,

We can see that Steven has conducted a hypothesis test to determine whether the true mean weight of basset hounds is less than 45.8 pounds.

To calculate the p-value for this test statistic,

Use a standard normal distribution table to determine the area under the curve to the left of the z-score of -1.5.

Using a standard normal distribution table,

Find that the area to the left of -1.5 is approximately 0.0668.

This means that there is a 6.68% chance of getting a sample mean of 45.8 or less assuming that the true population mean is actually 45.8.

Alternatively, we can use a calculator to find the p-value.

Using a calculator, we would input the z-score of -1.5 and the degrees of freedom (which is n-1, or 48 in this case) into the calculator.

This would give us a p-value of approximately 0.0668 as well.

Thus,

The p-value of the test statistic is approximately 0.0668.

Cait can bike 32 miles in the same amount of time that Carl can bike 24 miles. If Cait bikes 2 mph faster than Carl, how fast does Cait bike?

Answers

Let t = time in hrs for both to go 32 mi

Let s = Carl's speed in mi/hr

s + 2 = Caits speed in mi/hr

------------------------------------------------------------

Carl's equation:

(1) 24 = s · t

Cait's equation:

(2) 32 = (s+2) · t

-----------------------------------

(2) 32 = s · t + 2t

and

(1) s = 24/t

Plug (1) into (2)

(2) 32 = (24/t) · t + 2t

(2) 32 = 24 + 2t

(2) 2t = 8

(2) t = 4

and

(1) s = 24/4

(1) s = 6

The speed of Cait is 8 mph

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to different addition, subtraction, multiplication, and division arithmetic operations.

Let x be the time in hours for both to go 32 miles

Let y be Carl's speed

Then Caits speed  is = y+ 2

So, Carl's equation:

x y= 24

and, Cait's equation:

32 = (y+2) · x

32 = xy + 2x...............(1)

and, y = 24/x

Put the above value in equation (1)

(24/x) x + 2x = 32

2x+ 24 = 32

2x= 8

x=4

Also, y= 24/x= 24/4 = 6

Hence, speed of Cait is 8 mph

The exterior angle is 17x+7, and it is equal to the sum of the two marked angles inside the triangle.

Step-by-step explanation:

The quadratic with roots p and q can be written as ...

  (x -p)(x -q) = 0

  x² -(p+q)x +pq = 0

For p=(-1-√2)/3 and q=(-1+√2)/3, we have ...

  p +q = (-1-√2)/3 +(-1+√2)/3 = -2/3

  pq = ((-1-√2)/3)((-1+√2)/3) = (1 -2)/9 = -1/9

Then the quadratic is ...

Maria import special clay pots from Brazil. A shipment of 50 pots cost her $350. She then sells the pots at local fairs and art shows. On her last shipment she made a profit of $750. (1) What is the cost of 1 clay pot? (2) what is the total amount of sell in order to make the profit? (3) How much does she need to sell each pot in order to make the profit?

Answers

Answer:

Q 1) 7$ Q 2) 50 Q 3) 15$

Step-by-step explanation:

1) The cost of 1 claypot = $7

2) Total amount sold to yield the given profit = $1100

3) Amount to sell each pot to make the given profit = $22

We are given that;

Cost of 50 pots = $350

1) Since 50 pots costs $350, the cost of one pot will be;

Cost of 1 clay pot = 350/50 = $7 per clay pot

2) She made a profit of $750 on the 50 pots.

This means amount she sold in order to make the profit will be;

$350 + $750 = $1,100

3) Since total amount she sold to make the profit is $1,100, then amount each pot was sold to yield that profit on the 50 clay pots will be;

1100/50 = $22 per pot

Dan gets paid $46,925 a year. If he gets paid biweekly, how much does he make per pay period.

Answers

Answer:

$1804.81

Step-by-step explanation:

There are approximately 52 weeks in a year.

If he gets paid biweekly, he gets paid every 2 weeks.

52/2 = 26

He gets paid 26 times per year.

$46,925/26 = $1804.81

well if Dan makes 46,925 a year then we need to find out how much he makes every single month so since we know there are 12 months in a year so we were divide 46,925 by 12 and we would get 3910.41 and since he gets paid biweekly which means every two weeks we would divide that by two giving us 1955.20 meaning he gets paid 1955.20 every other week
