Columbia College advertises that the mean starting salary of its
graduates is $39,000. The committee for Truth in Advertising, an
independent organization, suspect that this claim is exaggerated
and decides to conduct a hypothesis test to seek evidence to
support its suspicious. A random sample of 100 graduates is used
and the mean salary of the sample is $37,000, standard deviation of
sample is $6,150. Use a 0.05 level of significance. Find also the
p-value.
