1. The goal is to see if there is statistical evidence that the fabric polyester will decay after being in soil. The fabric was left in damp soil for either 2 or 16 weeks, and the breaking strengths in pounds was measured: 2 Weeks 118 120 126 126 129 16 Weeks 98 110 110 124 140 (a) How many possible permutations of the data by group are there? There are (""), where m = sample size for group 1, n = sample size for group two. Thus, we have () = 252.
