1.9.6 Examining numerical data 1.38 Mammal life spans. Data were collected on life spans (in years) and gestation lengths (in days) for 62 mammals. A scatterplot of life span versus length of gestation is shown below.66 (a) What type of an association is apparent (b) What type of an association would you 100 between life span and length of gesta tion? expect to see if the axes of the plot were reversed, i.e. if we plotted length of gestation versus life span? 50 . .. -25 (c) Are life span and length of gestation independent? Explain your reasoning. 200 400600 Gestation (days) Created by Paint XExplanation / Answer
