Assuming that o = P2,600, testthe executive belief with level ofsignificance of 0.05. The production manager of a fruits canningfactory begins to suspect that, as a result ofobserving the machine operators, the 16 oz.can of fruits may be slightly filled beyondthe required weight. He takes a randomsample of 80 packed cans and finds that themean weight is 16.08 oz. with a standarddeviation of 0.04 oz. At 1% Level ofSignificance, can the production managerconclude that the fruit cans were beingoverfilled?
