Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected and the alcohol content of each bottle is determined. Let μ denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (7.8, 9.4) and suppose we want to test

H 0 : μ = μ 0 H 1 : μ ≠ μ 0

Which of the following values of μ 0 will lead one to fail to reject H 0? Select all that apply.

7.6

9.2

8.4

7.9

7.4

9.7

9.5

8.8

Answer #1

Given confidenc einterval is (7.8 , 9.4)

As the confiden ceinterval conatins the values from 7.8 to 9.4 will fail to reject H0

so, values are as : 9,2 , 8.4 , 7.9 , 8.8
