A chocolate factory produces 100g bars of chocolate. The weight of a chocolate bar is modelled as a random variable r. Quality control dictates that the average weight of a chocolate bar is 100g with a variance of 0.2g-. Each morning 10 chocolate bars are weighed. This morning their weights were 100g. 102g, 100.5g, 98g, 101g, 99.5g, 98g, 100g. 979. 101g. Based on this sample, should the factory manager conclude that the factory has failed its quality control test (p = 0.05)
