In preparation for upcoming wage negotiations with the union, the managers for the Bevel Hardware Company want to establish the time required to assemble a kitchen cabinet. A first line supervisor believes that the job should take 51 minutes on average to complete. A random sample of 26 cabinets has an average assembly time of 45 minutes with a population standard deviation of 11 minutes. Is there overwhelming evidence to contradict the first line supervisor’s belief at a 0.10 significance level? Assume the population of assembly times is approximately normally distributed. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
