Identify the lower quartile (q1), the median (q2), and the upper quartile (q3) for this data set.
{1, 2, 4, 5, 7, 7, 8, 9, 9, 10}
q1 = 1, q2 = 7, q3 = 10
q1 = 4, q2 = 7, q3 = 9
q1 = 2, q2 = 8, q3 = 8
q1 = 4.5, q2 = 7.5, q3 = 9.5

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.
