A random sample of 212 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 3.3, and the sample standard deviation was 1.25. Test at the 5% significance level the null hypothesis that the population mean rating is at most 3 against the alternative that it is larger than 3.

Calculate the decision statistic and state the conclusion of the test.
