Is there a difference between the variance in ages for full-time seasonal employees and part-time seasonal employees at Vail Resorts? A sample of 62 full-time employees had an s12 = 265.69. A sample of 78 part-time employees had an s22 = 190.44.
(a) Test for equal variances with α = .05.
(b) If you were to then test for equal mean ages between the two groups, would you use the pooled t statistic for the test statistic? Why or why not?
