1. According to the National Institute of Health, about 37% of high school seniors have vaped in the past year. Suppose that a survey contacts an SRS of 400 high school seniors and calculates the sample proportion, p , in this sample who have vaped in the past year. a. What is the mean of the sampling distribution of p ? b. Find the standard deviation of the sampling distribution of p. Round to the nearest thousandth. c. Draw the curve of the sampling distribution of p. d. What is the probability, in an SRS of 400 high school seniors, that between 35% and 40% of them have vaped in the past year? e. If the sample size were 900 rather than 400, how would this change the curve of the sampling distribution p?

im like 90% sure its a meme

step-by-step explanation:

good luck tho

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
