Test for significance for variances between the two purchases.

A sample of 25 concession stand purchases at the October 22 matinee of Bride of Chucky showed a mean purchase of $5.29 with a standard deviation of $3.02. For October 26 evening showing of the similar movie, for a sample of 25 purchases the mean was $5.12 with a standard deviation of $2.14. The means appear to be very close, but not the variances. At α = .05, is there the difference in variances? Show all steps clearly, including a design of the decision rule.
