x	3	6	12	16	26
y	60	95	140	154	181

(a) Make a scatter diagram of the data and visualize the line you think best fits the data. (Submit a file with a maximum size of1 MB.)

(c) Use a calculator to verify that(x) =63,(x²) =1121,(y) =630,(y²) =88,702,and(x y) =9,600. Computer. (Enter a number. Round your answer to three decimal places.) Asxincreases from 3 to26months, does the value ofrimply thatyshould tend to increase or decrease? Explain your answer.

Given our value ofr,yshould tend to remain constant asxincreases.Given our value ofr,yshould tend to decrease asxincreases. Given our value ofr,yshould tend to increase asxincreases.Given our value ofr, we can not draw any conclusions for the behavior ofyasxincreases.
