Question

Let x be the average number of employees in a group health insurance plan, and let y be the average administrative cost as a percentage of claims.

x	3	7	15	36	72
y	40	35	30	26	16 (b) Would you say the correlation is low, moderate, or strong? positive or negative? low and negative moderate and positive strong and negative moderate and negative low and positive strong and positive (c) Use a calculator to verify that ΣΧ-133, ΣΧ2-6763,2y-147, Ey2-4657, and ΣΧΥ-2903. Compute r. (Round your answer to three decimal places.) As x increases, does the value of r imply that y should tend to increase or decrease? Explain. Given our value of r, y should tend to increase 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 Given our value of r, we cannot draw any conclusions for the behavior of y as x increases.
