The distribution of rhesus monkey tail lengths is bell-shaped, unimodal, and approximately symmetric. The average tail length is 6.8 cm and the standard deviation is 0.44 cm. Roscoe has a tail that is 10.2 cm long. What conclusion can we make based on the information given? a. We can apply the empirical rule to conclude that Roscoe is a potential outlier because he falls more than three standard deviations away from the mean. b. We can apply the empirical rule...
