(IN SAS) Consider the text file called muscle which consists of paired data of individual's muscle mass and age. We want to examine this relationship. a. Begin by looking at a scatterplot and finding the correlation. Does the association look linear? How strong is it? b. Produce the necessary diagnostic plots to prepare to fit a regression model. c. Using this information, would you recommend going ahead and fitting a simple linear regression model to this data? (Do not fit the model yet, just answer yes or no and provide evidence) mass age 82.0 71.0 91.0 64.0 100.0 43.0 68.0 67.0 87.0 56.0 73.0 73.0 78.0 68.0 80.0 56.0 65.0 76.0 84.0 65.0 116.0 45.0 76.0 58.0 97.0 45.0 100.0 53.0 105.0 49.0 77.0 78.0
