2. [10 points] The table provided provides data on a sample of 54 wild black bears of assorted ages, including very young bears. The variables are... 0 Weight, in pounds. 0 Chest circumference (the distance around the chest), in inches. 0 Age, in months. The data set is also available here in StatCrunch. a. [2 points] Find the mean and standard deviation of the weights. Give correct units and follow appropriate rules of rounding. b. [1 point] Find 1", the correlation, between the weight and the chest circumference. Round your answer to three places after the decimal point.

[1 point] Find the equation of the least-squares regression line (also known as the line of best fit) that predicts the weight based on chest circumference. Round values to four places after the decimal point. e. [3 points] The equation of the best-fit line that predicts the chest circumference of a wild bear, based on its age, is y = 27.1327 + 0.197035. Find and interpret the slope and the yintercept of this line, including correct units. (It may not be appropriate or realistic to interpret the yintercept, but do it anyway.) e. [1 point] Use the equation from the previous problem to predict the chest circumference of a wild black hear if it is 24 months old. Round your answer to the nearest tenth, and use correct units
