question 14

Perform a hypothesis test for the population mean. Assume that preliminary data analyses indicate that it is reasonable to apply the z-test. Use the critical-value approach. 14) The Maine Department of Natural Resources reported that the 14) mean weight of lobsters trapped in the state is 1.7 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 of 45 lobsters that 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 than 1.7 pounds. Assume that the population standard deviation is 0.6 pounds
