If the production line is putting in an average of less than 8 chips per cookie the company will shut down the line for repairs. They take a sample of 25 cookies and find that the average number of chocolate chips per cookie in the sample was 6 with a sample standard deviation of 4. Assume that the number of chocolate chips in a cookie has approximately a symmetric distribution. Using , conduct a hypothesis test and state your conclusion. Be sure to follow all ten steps for a complete hypothesis test.
