A sample of 27 blue jelly beans with a mean weight of 0.8530 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 0.8500g (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? (round to two decimal places as needed.)
B. What are the critical values? (Round to to decimal places as needed.)
C. What is the P-Value? (round to four decimal places as needed. )
D. What is the final conclusion?
