The plant manager is concerned his equipment may need recalibrating. It seems that the actual weight of the 16-ounce cereal boxes it fiks has been fluctuating. The standard deviation should be at most 0.43 ounces. To determine if the machine needs to be recalibrated, 68 randomly selected boxes of cereal from the next day's production were weighed with the following results (in ounces): 15.5, 15.8, 15.9, 15.9, 16.3, 15.4, 16.4, 15.9, 15.5, 16, 16.9, 16.7, 15.3, 16.2, 15.5, 15.8, 16, 16, 15.2, 15.3, 15.5, 15.9, 15.7, 15.3, 16.1, 16.3, 15.3, 17, 17.1, 15.9, 15, 15.9, 15.9, 17.2, 15.5, 15.9, 15.8, 16, 16, 15.7, 16.3, 15.1, 16, 15.8, 16, 16.4, 15.7, 15.8, 16.2, 15.9, 15.7, 16.1, 16.2, 15.9, 16.4, 16, 15.8, 15.5, 16.3, 15.8, 15.1, 16.1, 16.3, 16, 16.1, 16.6, 16.3, 16.3 Perform a hypothesis test using a 1% level of significance to test if the equipment needs to be recalibrated.
