Summary statistics for the scores of the 27 students who completed a Dental Anxiety Scale questionnaire are x= 10.7 ands = 3.3. Scores range from 0 (no anxiety) to 20 (extreme anxiety). Conduct a test of hypothesis to determine whether the mean Dental Anxiety Scale score for th population of college students differs from u= 11. Use a0.01. State the null and alternative hypotheses. Choose the correct answer below. O A. Ho: u 11 versus H3: u= 11 O B. Ho: = 11 versus Ho: u> 11 OC. Ho: H= 11 versus Ha: H# 11 The test statistic for this small-sample test of a population mean is (Round to two decimal places needed.) Find the rejection region. Choose the correct answer below. O A. t> -2.779 and t<2.770 O B. t< -2.779 or t>2.770 Oc. t< -2.779 O D. t>2.779 State the appropriate conclusion for the test. Choose the correct answer below. There is sufficient evidence to reject Ho- There is insufficient evidence to reject Ho-

![Summary statistics for the scores of the 27 students who completed a Dental Anxiety Scale questionnaire are x= 10.7 and s= 3.3. Scores range from 0 (no anxiety) to 20 (extreme anxiety). Conduct a test of hypothesis to determine whether the mean Dental Anxiety Scale score for the
population of college students differs from u= 11. Use a= 0.01.
State the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: u# 11 versus Ha:p= 11
O B. Ho: H= 11 versus Hg: u> 11
O c. Ho: u= 11 versus Ha:P#11
The test statistic for this small-sample test of a population mean is
(Round to two decimal places as needed.)
Find the rejection region. Choose the correct answer below.
O A. t> -2.779 and t<2.779
O B. t< -2.779 or t> 2.779
Oc. t< -2.779
O D. t>2.779
