Refer to Exercise 7.18. The wildlife biologist was interested in determining if the mean weight of deer raised in a zoo would be lower than that of deer raised in a more uncontrolled environment—for example, raised either in the wild or on a ranch.
a. Use a multiple-comparison procedure to determine if the mean weight of the deer raised in the wild or on a ranch is significantly higher than the mean weight of deer raised in a zoo.
b. Write a linear contrast to compare the average weight of deer raised in a zoo or on a ranch to the mean weight of deer raised in the wild.
c. Test at the a = .05 level whether your contrast in part (b) is significantly different from zero. What conclusions can you draw from this test?
