As part of an analysis of the 2018 holiday sales season, J.Crew collected data from shoppers in stores in two locations - New York and Los Angeles. A sample of 40 shoppers in New York was collected which yielded an average purchase value of 68 with a standard deviation of 18. A sample of 42 shoppers in Los Angeles was collected which yielded an average purchase value of 58 with a standard deviation of 21. Assuming equal variance between the two cities and using a 95% confidence level (a = 0.05), is there evidence of a difference in the average purchase value between New York and Los Angeles? Justify your conclusion. As part of an analysis of the 2018 holiday sales season, J.Crew collected data from shoppers in stores in two locations - New York and Los Angeles.
