You wish to test the following claim (HaHa) at a significance level of =0.05=0.05. For the context of this problem, d=21d=2-1 where the first data set represents a pre-test and the second data set represents a post-test. Ho:d=0Ho:d=0 Ha:d>0Ha: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=118n=118 subjects. The average difference (post - pre) is d=3.6d=3.6 with a standard deviation of the differences of sd=16.3sd=16.3. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is...

• less than (or equal to)
• greater than

This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null

As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is greater than 0.
• There is not sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is greater than 0.
• The sample data support the claim that the mean difference of post-test from pre-test is greater than 0.
• There is not sufficient sample evidence to support the claim that the mean difference of post-test from pre-test is greater than 0.
