A clothing company has previously experimented with a promotional offer designed to increase sales. They sent a voucher to repeat customers, hoping it would entice them to buy additional items. The company is considering using the promotion again, but it wants to check to see if it is profitable. In order for the promotion to be profitable, the average customer needs to spend more than $95 when using the voucher. Data was gathered on 50 randomly selected transactions, and the average amount customers spent when using the voucher was $109.39 with a standard deviation of $48.22. Test the hypothesis that the promotion is profitable at the 5% significance level. Select the most appropriate null and alternative hypothesis for the problem.
