Consider the sample of 60 bottle design ratings given in Table 1.6. 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 α = .05, and note that x̅ = 30.35 and s = 3.1073 for the 60 bottle design ratings.
