1. The average weight of a group of individuals in a weight loss program was originally 200 pounds. After 2 weeks of the program, a sample of 60 such individuals are considered, and it is found that the average weight for these sampled individuals is 180 pounds with a standard deviation of 80 pounds. What would be the pair of hypotheses to test if the average weight has gone down. A. H0 : μ ≥ 200 vs Ha : μ < 200   B. H0 : μ > 200 vs Ha : μ < 200   C. H0 : μ <200 vs Ha : μ > 200   D. H0 : μ < 200 vs Ha : μ ≥ 200   2.What would be the standard error of the sample mean in problem 1? A. 1.15   B. 1.33   C. 10.33   D. 12   3. What would be the p-value for testing the pair of hypotheses in problem 1?   A. 0.1   B. 0.058   C. 0.05   D. 0.029
