Each of them are sent a surveyafter they graduate, and 27 of them are returned. The survey asks many things, chiefly among them howprepared they feel enterring the real world upon graduation. The results (on a scale of 1-10) show an averageof 7.3 with a standard deviation of 2.7. Is there significant evidence to conclude that the scores of theserecent graduates is different from 7 at the 0.01 significance level?

a. Null hypothesis: H0:µ=7. Alternative hypothesis: H1:µ≠7. H0:µ=7 vs H1:µ≠7.b. This is a two-tailed test. P-value for two-tailed test: P-value: The P-value is the probability of obtaining a test statistic value as extreme as the observed test statistic value, given that the null, H0 is true. Thus, P-value = 2PHo (test statistic ≠ observed value of test statistic). The probability statement for p-value is, 2P(T≠ test statistic). c. Decision rule: If p-value ≤α, then reject the null hypothesis. Otherwise, fail to reject the null hypothesis. Conclusion: Here, p-value (0.11) is greater than the level of significance (0.01). Therefore, fail to reject the null hypothesis. Fail to reject H0 because p-value >α.
