Can someone help me solve this? Thank you!

You wish to test the following claim (H.) at a significance level of o = 0.01. For the context of this problem, Add = /2 - wi where the first data set represents a pre-test and the second data set represents a post-test. Ho:Ha = 0 Ha: Pa 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 = 35 subjects. The average difference (post - pre) is d = - 7.2 with a standard deviation of the differences of $ = 47.4. a. What is the test statistic for this sample? test statistic = Round to 3 decimal places. b. What is the p-value for this sample? Round to 4 decimal places. p-value = c. The p-value is... O less than (or equal to) o O greater than o d. This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null e. As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is not equal to 0. O There is not sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is not equal to 0. The sample data support the claim that the mean difference of post-test from pre-test is not equal to 0. O There is not sufficient sample evidence to support the claim that the mean difference of post-test from pre-test is not equal to 0
