nonsufferers, respectively. Assume that the two distributions of heat output are normal with a- 0.1 and a2 - 0.5. (a) Consider testing Ho: H1 -H 2 --1.0 versus Hai H1-H is the same as that of non-sufferers. Ha says that the average heat output for sufferers is more than 1 cal/cm/min below that of non-sufferers. Ha says that the average heat output for sufferers is less than 1 cal/cm/min below that of non-sufferers. Calculate the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) P-value= State the conclusion in the problem context. Fail to reject Ho. The data suggests that the average heat output for sufferers is the same as that of non-sufferers. Fail to reject Ho. The data suggests that the average heat output for sufferers is less than 1 cal/cm/min below that of non-sufferers. Reject Ho. The data suggests that the average heat output for sufferers is more than 1 cal/cm/min below that of non-sufferers. Reject Ho. The data suggests that the average heat output for sufferers is the same as that non-sufferers.
