Example 10.4 Analysis of Alternative Turkey-Feeding Programs (Hypothesis Test for Differences Between Means) In this example we revisit the turkey-feeding problem from Example 10.1. In that example we used a matched-pairs test and concluded that the new feeding program did result in greater weight gain than the old program, using a = 0.025. In this example we 10.2. Tests of the Difference Between Two Normal Population Means: Independent Samples 375 27 solve the same problem. The hypothesis test from Example 10.1 is exactly the same in this example. However, here we assume that the two samples are independent and we do not have matched pairs. We use the same data file, Turkey Feeding, which contains the sample of weights for the old and new feeding programs
