Suppose that a researcher is interested in the effect of an exercise program on body weight among men. The researcher expects a treatment effect of 3 pounds after 15 weeks of exercise in the exercise program. In the population, the mean adult body weight for men is µ = 195.5 pounds, σ = 42.0. For all of the following, assume that α = .05, two-tailed. a. State the null and alternative hypotheses using symbols (if you have trouble using the equation editor or inserting symbols here, just write it out by hand and include in on the sheet of paper for part b)
