Hello,

I have an assignment. Can you help me, please?

According to an Internet source, per-capita beer consumption in North Dakota is 43.6 gallons per year (source: Thomas C. Frohlich, "States drinking the most beer," http://247wallst.com, June 30, 2015). Suppose a survey is designed to determine if the per-capita consumption has changed in 2016. A hypothesis test is to be conducted using a sample size of 1,500, a significance level of 0.01, and a standard deviation of 40. Determine the probability that the test will be able to correctly detect that the per-capita consumption has changed if it has declined by an average of 4 gallons.
