How much should a 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).
y 60 95 140 150 181
(a) Make a scatter diagram of the data. Then visualize the line you think best fits the data.
(b) Use a calculator to verify that Ex= 59, Ex² = 943, Ey=626, Ey² = 87,486, and Exy = 8,843.
Computer. (Round to 3 decimal places.)
