Nursing faculty at a local college were interested in seeing if there was a difference in the mean starting salaries for newly graduated registered nurses (RN) in Baltimore and Philadelphia.  One hundred randomly selected new Baltimore RN's showed a mean salary of $61,500 with a standard deviation of $8,500.   One hundred randomly selected new Philadelphia RN's had a mean salary of $65,275 with a standard deviation of $9,500.  Does this evidence show a difference in mean salaries using a 0.05 significance level? What is the t-stat and p-value? What is your decision for the hypothesis
