Drew wondered if the average age of students in AP Statistics classes in his high school is under 18. He randomly selected 10 AP Statistics students in his school and the data set is given below. Using the information from a previous survey, he has concluded that the population standard deviation for the age of AP Statistics students in his school is 1.23. Assume that the ages of students in AP Statistics classes in this high school are normally distributed.

17 19 18 17 15 18 16 17 17 16

Use a calculator to test whether the true age of AP Statistics students in his school is under 18. Identify the p-value from the calculator output, rounding to three decimal places.

Researchers claim that at most 18 % % of high school students smoke cigarettes. A high school principal thinks the claim is too low and conducts his own survey. He samples 300 students and finds that 78 of them smoke cigarettes. He tests the claim using α=0.01 α=0.01 . What is the result of his hypothesis test? Select one: a. The hypothesis test suggests that more than 18 % % of high school students smoke cigarettes. b. The hypothesis test...
