A sample of 27 blue jellybeans with a mean weight of 0.8580 g was taken. Assume that the standard deviation is known to be 0.0565 g. Consider a hypohesis test that uses a 0.05 significance level to test the claim that the mean weight of all jellybeans is equal to 0.8575 g (the weight necessary so that bags of jellybeas have the weight pronted on the package). Assume the weight of jellybeans is normally distributed.

a.) what is the test statistic?

b.) What are the critical values?

c.) What is the final conclusion?
