Determining the null and alternate hypotheses.

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 percent confidence interval for the mean contains the value 14.0

b. The 95 percent 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 percent 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"
