Transcribed Image Text:A random sample of 1,523 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 5.11, and the sample standard deviation was 1.32. Test at the 1%
significance level, against a two-sided alternative, the null hypothesis that the population mean is 5.
