Please answer it's important!! A national dog show had two types of poodles. This table shows height data, in inches, for the two types of poodles.
What number completes the sentence below? Type your answer in the box.

The difference, in inches, between the mean heights for the two types of poodles is
( Blank ) times the variation for either type.

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 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 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. given our value of r, y should tend to decrease as x increases.
