Consider independent simple random samples that are taken to test the amTerence between the means of two populations. The variances of the populations are unknown but are assumed to be equal. The sample sizes of each population are n1 = 46 and n2 = 54. The appropriate distribution to use is the O t-distribution with df = 100 O t-distribution with df = 99 t-distribution with df = 50 O t-distribution with df = 98
