The college of science at a particular university has 336 alum in a given year. Each of them are sent a survey after they graduate, and 24 of them are returned. The survey asks many things, chiefly among them how prepared they feel enterring the real world upon graduation. The results (on a scale of 1-10) show an average of 6.6 with a standard deviation of 2.8. Is there significant evidence to conclude that the scores of these recent graduates is different from 6 at the 0.01 significance level? Note that there's evidence that this distribution is symmetric. What are the hypotheses? O Ho:H < 6 vs H1:42 6 O Ho:H 6 vs Hị:µ= 6 O Ho:4 < 6 vs H1:µ > 6 O Ho:H = 6 vs H1 :µ # 6 What is probability statement for the p-value? O P(T > test statistic) OP(Z > test statistic) O 2P(Z # test statistic) O 2P(T + test statistic) O None of the above If the p-value were to be 0.009, state and justify your decision. O Fail to reject Ho because the p-value < a. O Accept Ho because the p-value > a. O Reject Ho because the p-value < a. O Accept Ho because the p-value < a. O Fail to reject Ho because the p-value > a. O Reject Ho because the p-value > a.
