The document discusses a statistical analysis involving two independent simple random samples to test the difference between the means of two populations with unknown but assumed equal standard deviations. It specifies the sample sizes as n1 = 45 and n2 = 50, indicating that the t distribution should be used with the appropriate degrees of freedom for the analysis. The degrees of freedom are stated as 93, 94, 96, and 97.

1. Two independent simple random samples are taken to test the difference between the means of
two populations whose standard devations are not known, but are asgumed to be equal. The
sarmiple sizes are n 1 = 45 and n 2 = 50 . The correct distribution to vse is the t distribution with
degrees of freedom. 93 94 96 97
