Healthy Shetland pony weigh? Let x be the age of the pony (in months), and let y be the average weight of the pony (in kilograms). X 3 6 y 60 95 12 140 18 151 26 174 (a) Make a scatter diagram of the data. Then visualize the line you think best fits the data. (b) Would you say the correlation is low, moderate, or strong? Would you say the correlation is positive or negative? (c) Use a calculator to verify that Σx = 65, Σ x2 = 1189, ΣΥ = 620, Σy = 85,302, and Σ xy = 9,672. Computer. As x increases from 3 to 26 months, does the value of r imply that y should tend to increase or decrease? Explain your answer.
