Tom Sevits is the owner of the Appliance Patch. Recently Tomobserved a difference in the dollar value of sales between the menand women he employs as sales associates. A sample of 40 daysrevealed the men sold a mean of $1,400 worth of appliances per day.For a sample of 50 days, the women sold a mean of $1,500 worth ofappliances per day. Assume the sample standard deviation for men is$200 and for women $250. At the 0.05 significance level, can Mr.Sevits conclude that the mean amount sold per day is larger for thewomen? (Assume unequal variances. Report t test statistic, criticalvalues in 4 decimals)
The steps for testing whether the population mean sales forwomen is greater than the population mean sales for men is listedbelow for a significance level of 0.05. Fill in the blanks.
