Perform a hypothesis test for the population mean. Assume that preliminary data analyses indicate that it is reasonable to apply the z-test.

The Maine Department of Natural Resources reported that the mean weight of lobsters trapped in the state is1.7 pounds. Carl Lewis is a lobster trapper off the coast of Maine. Carl suspects that this figure is too high so he records the weights of a random sample of46 lobstersthat he trapped. The mean weight of the lobsters in the sample was 1.5 pounds. Using a 1% level of significance, perform a hypothesis test to determine whether the population mean is lower than1.7 poundsAssume that the population standard deviation is0.6 pounds

A) Reject H0: = 1.7 pounds. There is sufficient evidence to support the claim that the mean is lower than 1.7 pounds.

B) Fail to reject H0: = 1.7 pounds.There is not sufficient evidence to support the claim that the mean is lower than 1.7 pounds.
