7.18

A wildlife biologist was interested in determining the effect of raising deer in captivity on the size of the deer. She decided to consider three populations: deer raised in the wild, deer raised on large hunting ranches, and deer raised in zoos. She randomly selected eight deer in each of the three environments and weighed the deer at age 1 year. The weights (in pounds) are given in the following table.

Environment Weight (in pounds) of Deer

Wild	114.7	128.9	111.5	116.4	134.5	126.7	120.6	129.59
Ranch	120.4	91.0	119.6	119.4	150.0	169.7	100.9	76.1
Zoo	103.1	90.7	129.5	75.8	182.5	76.8	87.3	77.3

a. The biologist hypothesized that the weights of deer from captive environments would have a larger level of variability than the weights from deer raised in the wild. Do the data support her contention?

b. Are the requisite conditions for the test you used in part (a) satisfied in this situation? Provide plots to support your answer.
