You wish to test the following claim (H) at a significance level of a = 0.10. For the context of this problem, d = 421 where the first data set represents a pre-test and the second data set represents a post-test. Ho: d = 0 Ha: Pd > 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 = 198 subjects. The average difference (post-pre) is d = 6 with a standard deviation of the differences of sd = 32.4. 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... O less than (or equal to) a Ogreater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null
