Cruise ship sanitation scores. Refer to the data on the Aug. 2013 sanitation scores for 186 cruise ships, presented in Exercise 2.41 (p. 51). The data are saved in the SANIT file. Assess whether the sanitation scores are approximately normally distributed. (p. 91). Recall that for each of 550 Southwest Pacific islanders, the effect of the mutation on hair pigmentation was measured with the melanin (M) index, where M ranges between -4 and 4. Box plots showing the distribution of M for three different genotypes—CC, CT, and TT—are reproduced below (left column). Use the guidelines of this section and Exercise 5.51 (p. 274) to determine whether any of these distributions are normally distributed.
