1. An account on Server A is more expensive than an account on Server B. However, Server A is faster. To see if it is optimal to go with the faster but more expensive server, a manager needs to know how faster it is. A certain computer algorithm is executed 15 times on Server A and 10 times on Server B with the following results: Server A Mean 6.? mins 7.5 mins Standard Deviation 0.6 mins 1.2 mins At a = 0.10, is there enough evidence to conclude that the average speed for Server A is higher than the average speed for Server B? Use the p-value method. 2. Twentyr users were asked to add a contact to a customer relationship management software (CRM) application. Eleven users completed the task on the existing version and nine different users completed the same task on the new enhanced version. The sample means are 3? and 28 seconds, respectively. The sample standard deviations are 22.4 and 9.4 seconds, respectively. Is there enough evidence to conclude a difference in the average time for adding a contact between the two versions? Use the rejection point method. Use a = 0.05
