A data set is given below. (a) Draw a scatter diagram. Comment on the type of relation that appears to exist between $x$ and $y$. (b) Given that $\stackrel{?}{x}=3.5000,s_x=2.5100,\stackrel{?}{y}=4.0833,s_y=1.9416$, and $r=?0.9501$, determine the least-squares regression line. (c) Graph the least-squares regression line on the scatter diagram drawn in part (a). (a) Choose the correct graph below. A. B. There appears to be (b) $\hat{y}=x+$, (Round to three decimal places as needed.) (c) Choose the correct graph below. c. D.
