a) Which of the following must be satisfied in order for the parametric test to be valid? I. The difference in weight between pairs of chicken are normally distributed. II. The weight of chickens from each supplier are normally distributed. A. I only B. Il only C. Both I and II D. Neither I nor II b) Suppose one of the assumptions for the parametric test was not satisfied. The appropriate test procedure to be used is A. t-test for related samples B. t-test for independent samples C. Mann-Whitney U test D.

1. The management of ANDOK's chicken observed a significant increase in demand for grilled chicken during the holidays. However, suppliers of quality chicken are also limited during these days. For this year's preparation, Max Poultry and Chooks Manukan suppliers were selected for evaluation. From each supplier, 10 chickens were randomly selected and grilled. It is of interest to test whether there is a difference between the mean weights of chicken from the two suppliers. a) Which of the following must be satisfied in order for the parametric test to be valid?
