Question 4 (Two parts; 12 marks in total): A certain marine species is generally quite slow at swimming. However, a few individuals learn to swim very fast, creating outliers in swimming speeds. Below is a table of data showing the swimming speeds of random samples of this species in three island countries in the Indian Ocean and histograms illustrating the three distributions. Below that are the results of the Shapiro-Wilk, first based on the original data and, second, based on natural log transformed data (In). Use this information to answer parts (a) and (b).
