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 59 minutes on average to complete. A random sample of 21 cabinets has an average assembly time of 55 minutes with a population standard deviation of 9 minutes. Is there overwhelming evidence to contradict the first line supervisor's belief at a 0.01 significance level? Assume the population of assembly times is approximately normally distributed. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho μ= 59 Ha H. .59
