The First Night Stage Company

The First Night Stage Company operates a small, nonprofit theater group in Milwaukee. Each year, the company solicits donations to help fund its operations. This year, it obtained the help of a marketing research company in the city. This company’s representatives proposed two different solicitation brochures. They are interested in determining whether there is a difference in the standard deviation of dollars returned between the two brochures. To test this, a random sample of 20 people was selected to receive brochure A and another random sample of 20 people was selected to receive brochure B. The data are contained in the file called First-Night. Based on these sample data, what should the First Night Company conclude about the two brochures with respect to their variability? Test using a significance level of 0.02.
