Assume that a 95 confidence interval for the mean is 145 1

Assume that a 95% confidence interval for the mean is 14.5 < < 16.0. The null hypothesis H₀: = 15.0 at = 0.05 would

A) not be rejected because 15.0 is less than 16.0.

B) not be rejected because 15.0 is between 14.5 and 16.0.

C) be rejected because 15.0 is more than 14.5.

D) be rejected because 15.0 is not equal to 15.25.

Solution

B) not be rejected because 15.0 is between 14.5 and 16.0.

i.e, it is plausible that true mean is 15 because 15 is inisde the CI
