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

Possible answers:

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 15.15
