1. Assume that in a hypothesis test with null hypothesis H0 : μ = 14.0 at a = 0.05, that a value of 13.0 for the sample mean results in the null hypothesis not being rejected. That corresponds to a confidence interval result of:

a. The 95% confidence interval for the mean contains the value 14.0

b. The 95% confidence interval for the mean does not contain the value 14.0

c. There is insufficient information as to if the 95% confidence interval for the mean does or does not contain the value 13.0

d. The 0.05% confidence interval for the mean contains the value 13.0

2. For the conjecture "The average age of students in this class is 20", the null hypothesis is

a. H0: μ = 20"

b. H0: μ = 20"

c.H0: μ = 20"

d. H0: μ = 20"
