Extracted text: 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). 3 12 15 21 y 60 95 140 164 175 (b) Would you say the correlation is low, moderate, or strong? O low O moderate O strong Would you say the correlation is positive or negative? O positive O negative (c) Use a calculator to verify that 'x = 57, x² = 8 y = 634, y² = 89,746, and xy = 8,565. 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. O Given our value of r, y should tend to remain constant as x increases. O Given our value of r, y should tend to decrease as x increases. O Given our value of r, we can not draw any conclusions for the behavior of y as x increases. O Given our value of r, y should tend to increase as x increases.
