**Question 2**You wish to test the following claim ($H_0$) at a significance level of $\alpha = 0.01$. For the context of this problem, $\mu_d = \mu_2 - \mu_1$ where the first data set represents a pre-test and the second data set represents a post-test.\[ H_0: \mu_d = 0 \]\[ H_a: \mu_d < 0 \]You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for $n = 19$ subjects. The average difference (post - pre) is $\bar{d} = -17.9$ with a standard deviation of the differences of $s_d = 48.7$.**What is the critical value for this test?** (Report answer accurate to two decimal places.)critical value = $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$**What is the test statistic for this sample?** (Report answer accurate to three decimal places.)test statistic = $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$The test statistic is…- ( ) in the critical region- ( ) not in the critical regionThis test statistic leads to a decision to…- ( ) reject the null- ( ) accept the null- ( ) fail to reject the nullAs such, the final conclusion is that…- ( ) There is sufficient evidence to warrant accepting the Ho: the mean difference is zero vs. Ha: the mean difference is less than 0.- ( ) There is not sufficient evidence to warrant accepting the Ho: the mean difference is zero vs. Ha: the mean difference is less than 0.- ( ) The sample data support rejecting the Ho: the mean difference is zero vs. Ha: the mean difference is less than 0.- ( ) There is not sufficient sample evidence to support rejecting the Ho: the mean difference is zero vs. Ha: the mean difference is less than 0.
