The company Pro Fish Sales Directors (PFSD ehf.) Maintains a sales department in Alaska and New York. The capelin shortage has put the company in a tight spot and either division needs to be closed. PFSD has obtained samples of sales figures from both places and wants to get you to help decide which department to close. The samples are independent and the company has decided that the decision will be made based on a 95% confidence interval on average sales. In Alaska, the average sale of the sample was ISK 580. a day. The number of sales examined was 29 and the standard deviation is ISK 27. a day. In New York, 11 sales were inspected, the average sales was ISK 500. per day and the standard deviation was ISK 99. a day.
a) PFSD ehf. assumes that the distribution in the sales of the departments is equal. Which division should the company close and why?
