A) Mo has been rounding decimal numbers to the nearest whole number. Put a * by the correct answers and correct the incorrect answers. Number Rounded to Whole Number Correct (*) or Correction 7.2 7 * 8.5 8 9 12.9 13 * 3.4 3 * 11.5 11 12 9.5 9 10 b) Mo has made the same mistake throughout. Explain to Mo the mistake he has made. A:

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.
