Pull up the StatCrunch data set titled Bear Measurements Data Set created by Imazaleski. Use the values for the chest and age of the bears to answer the questions below. To make sure we understand the data, keep the following in mind: Age is the bear's age in months Month is the month the measurements were taken Head Length is the length of the head in inches Head Width is the width of the head in inches Length is the length of the body in inches Neck is the distance around the neck in inches Chest is the distance around the chest in inches Weight is in pounds a. What is the value of r (correlation coefficient)? Is there linear correlation between the 2 variables? Explain. b. Identify the dependent variable and the independent variable. c. What is the equation of the least-squares regression line?
