A random sample of n = 50 individuals is obtained from a population with a mean of µ = 736. A treatment is administered to each individual in the sample and, after treatment, is measured. The average score for the treated sample is M = 732 with SS=962. Use a 2-tailed test with a critical value at .05. %3D
