question 21

Multiple Choice

Assume that a 99% confidence interval for the mean is (11.5, 13.0) . Then a hypothesis test of $\mathrm { H } _ { 0 } : \mu =$ $12.0 \text { at } a = 0.01$ would result in

• A) Accepting the null hypothesis because 12.0 is less than 13.0
• B) Accepting the null hypothesis because 12.0 is between 11.5 and 13.0
• C) Rejecting the null hypothesis if because 12.0 is more than 11.5
• D) There is insufficient information to make any conclusions about the hypothesis test
