# Question

On the basis of a random sample the null hypothesis
H0: μ = μ0
is tested against the alternative
H1: μ > μ0
and the null hypothesis is not rejected at the 5% significance level.
a. Does this necessarily imply that μ0 is contained in the 95% confidence interval for m?
b. Does this necessarily imply that μ0 is contained in the 90% confidence interval for m if the observed sample mean is larger than μ0 ?
