A random sample of 22 American India Pale Ales (IPAS) was selected and their alcohol by volume (ABV) was recorded in the data set “Sample of Beer’s ABV". Using a = 0.10, is there sufficient evidence to conclude the average ABV of IPAS different from the standard 6% (0.06 ABV)? Conduct a full hypothesis test by following the steps below. Enter an answer for each of these steps in your document. You can assume the population size of American India Pale Ales is 2100 different kinds. %3D a) Define the population parameter in context in one sentence. b) State the null and alternative hypotheses using correct notation. c) State the significance level for this problem.
