Suppose you are interested in testing whether the mean earnings of men in the General Social Survey is representative of the earnings of the entire U.S. male population. Further, suppose that the average male in the General Social Survey earned $31,607 in 2005 and that the

average male in the population earned $33,405 in 2005. There are 372 men in the General Social Survey.

a.State the null and research hypotheses.

b.Calculate the degrees of freedom for this one-sample t-test

c.You are trying to determine if the GSS sample is different than the US population, but you don’t have a theoretical reason to say if the sample is higher or lower than theUS population. Should you use a one-tailed test or a two-tailed test? Why?
