Samples are taken from two independent populations, and the following statistics are computed: n1=50, x bar 1=175 , s1=20.5, n2=42, x bar 2=158, s2=34.9. If these samples are to be used to test for a difference between the means of the two populations, how many degrees of freedom does the appropriate test statistic have?

Check your text. Maybe it will be the smaller of (sample size One - 1) and (sample size Two - 1) and not the "more precise" one attached. http://stattrek.com/hypothesis-test/difference-in-means.aspx
