Ring-Necked Pheasants The weights in grams of 10 males and 10 female juvenile ring-necked pheasants are given below.

a. Use a statistical test to determine if the population variance of the weights of the male birds differs from that of the females.

b. Test whether the average weight of juvenile male ring-necked pheasants exceeds that of the females by more than 300 grams. (HINT: The procedure that you use should take into account the results of the analysis in part a.)
