Question:

Xr13-82 In Exercise 12.66, we described the problem of whether to change all the lightbulbs at Yankee Stadium or change them one by one as they burn out. There are two brands of bulbs that can be used.

Because both the mean and the variance of the lengths of life are important, it was decided to test the two brands. A random sample of both brands was drawn and left on until they burned out. The times were recorded. Can the Yankee Stadium management conclude that the variances differ?
