A random sample of 171 marketing students was asked to rate, on a scale from 1 (not important) to 5 (extremely important), health benefits as a job characteristic. The sample mean rating was 4.09, and the sample standard deviation was 0.6. Test at the 5% significance level the null hypothesis that the population mean rating is at most 4 against the alternative that it is larger than 4

4. A random sample of 1,557 undergraduates enrolled in management ethics courses was asked to respond on a scale from 1 (strongly disagree) to 7 (strongly agree) to the proposition that senior corporate executives are interested in social justice. The sample mean response was 3.10, and the sample standard deviation was 1.24. Test at the 1% significance level, against a two-sided alternative, the null hypothesis that the population mean is 3.0.
