1)A. Use a calculator to verify that Σx = 24.0,
Σx2 = 85.48, Σy = 53.3,
Σy2 = 458.51 and Σxy = 189.96.
Compute r. (Round to 3 decimal places.)
B.As x increases, does the value of r imply that
y should tend to increase or decrease? Select one.
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 decrease 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.

don't get the size of data set. If you have then put the value of
the formula of r and interpret it as per my explanation.
