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). x 3 12 17 25 y 60 95 140 160 187 LA USE SALT (a) Make a scatter diagram of the data and visualize the line you think best fits the data. 25 25 20 2 2 140 15 rage weight (in 13 y (average weight (in kg)) 120 y average weight 10 100 y (avera en 60 80 100 120 140 160 180 10 15 25 60 20 80 100 120 140 160 180 x (age (in months)) x (age (in months)) x (age (in months)) G y (average weight (in kg)) 10 15 20 25 x(age (in months)) (b) Would you say the correlation is low, moderate, or strong? low moderate strong Would you say the correlation is positive or negative? positive negative (c) Use a calculator to verify that _x = 63, _x? = 1103, Ly = 642, Ly2 = 92,794, and xy = 9,825. Computer. (Round your answer to four decimal places.) As x increases from 3 to 25 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. Given our value of r, y should tend to decrease as x increases. Given our value of r, y should tend to increase as x increases. Given our value of r, we can not draw any conclusions for the behavior of y as x increases. Given our value of r, y should tend to remain constant as x increases. MacBook Air DII DD
