Score: 0.33 of 1 pt 1 69 oft-35 (85 complete)v ) HW Score: 97.1%, 82.53 of 85 pts @ 5.11.9 Question Helpv a A sample of 27 bluejellybeans with a mean weight of 0.8540 g was taken. Assume that 6 is known to be 0.0565 g. Consider a hypothesis test that uses a 0.05 signicance level to test the claim that the mean weight of all jellybeans is equal to 0.8505 g (the weight necessary so that bags of jellybeans have the weight printed on the package). Assume the weight ofjellybeans is normally distributed. (a) What is the test statistic? z = .32 (Round to two decimal places as needed.) (b) What are the critical values? (Round to two decimal places as needed. Use a comma to separate answers as needed.)
