Untitled Stem and leaf plot. Vertical line separates each stem number from its first leaf number. First row. Stem 1. Leaves 4, 5, 7. Second row. Stem 2. Leaves 1, 2, 4, 4, 6. Third row. Stem 3. Leaves 0, 2. Key. 2 vertical line 1 means 21.

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.
