An experiment is planned to compare the mean of a controlgroup to the mean of an independent sample of a group given atreatment. Sppose that there are to be 25 samples in each group.Suppose that the observations are approximately normallydistributed and that the standard deviation of a single measurmentn eiter group is =5. (Answer in the parantheses) d) Suppose that the p-value of the test turns out to be0.07. Would the test reject at significant level = .10? (The answeris yes, can you tell me why).

Explanation / Answer
Since P - value = 0.07 < = 0.10, we have to reject the test at 10% level of significance.
