Question

Consider the sample of 60 bottle design ratings given in the table (below). A Sample of Bottle Design Ratings (Composite Scores for a Systematic Sample of 60 Shoppers) 29 23 39 35 33 15 27 15 36 20 1 6 20 21 15 32 31 36 25 40 30 17 38 21 21 18 37 24 27 40 28 24 16 32 26 39 15 34 28 34 16 39 21 19 38 33 16 36 37 40 40 35 20 Use these data to carry out a chi-square goodness-of-fit test to determine whether the population of all bottle design ratings is normally distributed. Use a = .05, and note that i = 27.50 and s = 8.4402 for the 60 bottle design ratings. Use the Empirical Rule to create the intervals. (Round your answer to 3 decimal places.) x²= 9.060 Reject A Ho; the population of all bottle design ratings are not normally distributed.
