(b) Would you say the correlation is low, moderate, or strong?
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 = 61, x² = 1021, y = 646, y = 93,886, and xy = 9,494.

Compute r. (Round your answer to four decimal places.)
As x increases from 3 to 24 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 decrease as x increases.
O Given our value of r, y should tend to increase 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 remain constant as x increases.
