oduce the product only if the average response to a 5-point scale question (where 5 = Strongly Prefer) is better than 4.0. Please set up the appropriate hypothesis test and do the first three steps (use an á value of 0.05). Then, use these data: Sixty-four people answer the question. You calculate the average response to be 4.5 on a 5-point scale, and the standard deviation (Sx) is 2.
How will you state the Null and Alternate Hypotheses [2 points]?
