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 α = .05, and note that x¯�¯ = 44.93 and s = 5.5200 for the 60 bottle design ratings. Use the Empirical Rule to create the intervals. (Round your answer to 3 decimal places.)
