**Hypothesis Testing in Dental Anxiety Scale**Summary statistics for the scores of 27 students who completed a Dental Anxiety Scale questionnaire are as follows: the mean score ($\bar{x}$) is 10.5, and the standard deviation (s) is 3.3. Scores range from 0 (no anxiety) to 20 (extreme anxiety). Conduct a hypothesis test to determine whether the mean Dental Anxiety Scale score for the population of college students differs from $\mu = 11$. Use $\alpha = 0.05$.**State the Null and Alternative Hypotheses:**Select the correct answer below.A. $H_0$: $\mu = 11$ versus $H_a$: $\mu \neq 11$B. $H_0$: $\mu \neq 11$ versus $H_a$: $\mu = 11$C. $H_0$: $\mu = 11$ versus $H_a$: $\mu > 11$*Correct Answer: A. $H_0$: $\mu = 11$ versus $H_a$: $\mu \neq 11$***Test Statistic:**The test statistic for this small-sample test of a population mean is \[ t = \frac{\bar{x} - \mu}{s/\sqrt{n}} = 0.79 \](Round to two decimal places as needed.)**Rejection Region:**Choose the correct answer below.A. $ t > -2.056 \text{ and } t < 2.056 $B. $ t < -2.056 $C. $ t > 2.056 $D. $ t < -2.056 \text{ or } t > 2.056 $*Correct Answer: D. $ t < -2.056 \text{ or } t > 2.056 $*
