In the past, the average production of employees of a Generation Inc. has been 42,000 units. Recently, the company has been hiring more experienced workers. In order to determine whether there has been an INCREASE in the average production of all the employees, a sample of 36 employees was selected. The average production in the sample was 45,000 units with a standard deviation of 6,000 units. Assume the distribution of the population is normal (Hint: this does not mean that the distribution of the sample mean is normal). Let a = .05. a. State the null and the alternative hypotheses. b. What is the value of the test statistic? C. What is the p-value?
