The label of caviar cans of a certain brand states that they contain a net weight of 50 grams. It is given that the net weights of the cans are normally distributed with a standard deviation of 1.5 grams. To see whether the claim on the label is true, a sample of 36 cans is taken. The obtained sample mean of net weights is 49.5 grams. [Problem I] Test the null hypothesis that the average net weight of caviar cans is 50 grams against the alternative hypothesis that this average is smaller than 50 grams. Use a significance level of 5%. [20] [Problem II] Compute the power of the test in (b) if the actual average net weight of caviar cans is 49.3 grams.
