One cable company claims that it has excellent customer service. In fact, the company advertises that a technician will arrive within 50 minutes after a service call is placed. One frustrated customer believes this is not accurate, claiming that it takes over 50 minutes for the cable technician to arrive.
The customer asks a simple random sample of 16 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 56.2 minutes with a standard deviation of 12.6 minutes. Assume that the population distribution is
approximately normal. Test the customer's claim at the 0.10 level of significance.
Step 2 of 3: Compute the value of the test statistic. Round your answer to three decimal places.
