6. Suppose that we do not know that the distribution of weights of the individual cans is Normal, and we do not know the standard deviation, o, of the distribution of weights. This is closer to what would happen in practice. We obtain a random sample of n = 225 cans. The average weight is found to be X = 94.8 g and the standard deviation is 8 = 1.4 g, based on the sample. What is the p-value if the population mean is j = 95 g
