Q4

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) 21 18 25 20 17 19 12 27 14 40 31 21 19 14 15 14 37 17 36 31 13 21 45 37 33 16 26 12 38 26 18 27 21 20 22 23 31 33 12 38 29 18 39 15 26 41 39 13 23 14 31 26 17 40 17 17 14 36 31 17 Use these data to carry out a chi-square goodness-of-fit test to determine whether the population of all waiting times is normally distributed. Use a = .05, and note that @ = 25.20 and s= 9.8494 for the 60 bottle design ratings. Use the Empirical Rule to create the intervals. (Round your answer to 3 decimal places.) x12 HO. the population of all bottle design ratings normally distributed
