One cable company claims that it has excellent customer service. In fact, the company advertises that a technician will arrive within 60 minutes after a service call is placed. One frustrated customer believes this is not accurate, claiming that it takes over 60 minutes for the cable technician to arrive. The customer asks a simple random sample of 25 other cable customers how long it has taken for the cable technician to arrive when they have called for one. The sample mean for this group is 63.4 minutes with a standard deviation of 15.1 minutes. Assume that the population distribution is approximately normal. Test the customer's claim at the 0.025 level of significance. Step 2 of 3: Compute the value of the test statistic. Round your answer to three decimal places.
