Q1) Harriet's Shoe Emporium runs stores in enclosed shopping malls in addition to outlet malls. There are more than 1,000 stores all through United States and Canada. Harriet, CEO, wants to find out whether number of shoes sold per week at mall stores is more than number sold at outlet malls. She chooses a sample of 22 mall and 25 outlet stores and finds out number of shoes sold in each sample store last week. Sample information is reported below.

Harriet believes there is much more variation in number of shoes sold in mall stores than in outlet stores. Therefore, she is not eager to suppose equal population standard deviations. At.02 significance level is it sensible to conclude that mean number of shoes sold at mall stores is larger than at outlet stores?
