A national caterer determined that 87% of the people who sampled their food said that it was delicious. A random sample of 144 people is obtained from a population of 5000. The 144 people are asked to sample the caterer's food. If ModifyingAbove p with caret is the sample proportion saying that the food is delicious, what is the mean of the sampling distribution of ModifyingAbove p with caret? A. 0.19 B. 0.42 C. 1.25 D. 0.87

(D)0.87

Step-by-step explanation:

DEFINITION

The mean of the sampling distribution of the sample proportion is equal to the population proportion.

Given that out of the random sample of 144, 87% said that it was delicious

Therefore, the Population proportion = 87%

The sample size of 144 from 5000 will have proportion which will follow a normal distribution with mean p = 87%

Hence the mean of the sampling distribution of is 0.87

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer: i guess 105 degrees?
