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	6	12	15	21
y	60	95	140	172	173

(a) Make a scatter diagram of the data and visualize the line you think best fits the data.

A scatter diagram has a horizontal axis labeled "x (age (in months))" with values from 60 to 173 and a vertical axis labeled "y (average weight (in kg))" with values from 3 to 21. The scatter diagram has 5 points. A pattern goes up and right from (60, 3) to (173, 21).

(b) Would you say the correlation is low, moderate, or strong?

lowmoderate strong

Would you say the correlation is positive or negative?

positivenegative

x = 57,

x² = 855,

y = 640,

y² = 91,738,

and

xy = 8,643.

Compute r. (Round your answer to four decimal places.)

As x increases from 3 to 21 months, does the value of r imply that y should tend to increase or decrease? Explain your answer.

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. Given our value of r, y should tend to increase as x increases.Given our value of r, y should tend to decrease as x increases.
