A sample of 27 blue jellybeans with a mean weight of 0.8510 g was taken. Assume that sigma is known to be 0.0565 g. Consider a hypothesis test that uses a 0.05 significance level to test the claim that the mean weight of all jellybeans is equal to 0.8490 g (the weight necessary so that bags of jellybeans have the weight printed on the package). Assume the weight of jellybeans is normally distributed.(a) What is the test statistic?(b) What is the critical value?(c) What is the p-value?(d) What is the final conclusion?
