The owner of the heating and air-conditioning company has two employees that make service calls. He is interested in the number of service calls made per day. The sample standard deviation for employee A is 1.05 calls per day and 1.23 calls per day for employee B. A random sample 40 days last year showed that employee A made an average of 4.67 calls per day. For a sample of 40 days employee B made an average of 5.02 calls per day. After the 0.05 significance level, is there a difference in the number of calls per day between the two employees? What is the alternative hypotheses and p-value?
