How can the mean of the values in a numerical data set be calculated? A
Order the values in the data set from least to greatest, then find the middle value.
B. Find the sum of the values in the data set, then divide by the middle value in the set.
с
Find the sum of the values in the data set, then divide that sum by the number of values in the set
D
Order the numbers in the data set from least to greatest, then subtract the least value from the greatest value.

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.
