A golf balls manufacturer requires that the weights of its golf balls have a standard deviation that is less or

equal 0.08 ounces. One of the quality control inspectors says that the machines need to be recalibrated because he

believes (claims) the standard deviation of the weighs of the golf balls is more than 0.08 ounces. To test the

machines, he selects a random sample of 50 golf balls off the assembly line and finds that they have a mean weight

of 1.56 ounces and a standard deviation of 0.0806 ounces. At the 0.01 level of significance, test the inspector's

claim.
