Decision statistic and last part?

A random sample of 1,560 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
uetice. The sample mean response was 3.04, and the sample standard deviation was 1.28. Test at the 5% significance level, against a two-sided alternative, the null hypothesis that the population mean is 3.
