Question: After a fire, a company can find only a few of its records. The accounting department was about to test the difference between the average sales per customer for two of the company's stores. The recovered records, consisting of only a few customer accounts produced the following results. Based on this small sample, and using a 0.05 significance level, is one store selling more per customer than the other?

The sample results are:

Store \(1, \bar{X}_{1}=\\) 53.87, s_1 =\$ 10.41, \mathrm{n}_{1}=18$

Store \(2,\quad {{\overline{\text{X}}}_{2}}=\\)68.13,{{s}_{2}}=\$11.94,{{n}_{2}}=22$
