Assuming 2004 is the explanatory variable and 2006 is the response variable, use your calculator to determine the following values. Round monetary values to the nearest whole million, round the slope to the nearest thousandth, and round the correlation coefficient to the nearest ten-thousandth. X = $ million Sx = $ million y = $ million Sy = $ million r= slope = million dollars/million dollars y-intercept = $ millionQUESTION 7 Suppose you find the correlation coefficient for butterfly lifespan vs their wingspan to be about -0.412. What percent of the variation in the butterfly lifespans is explained by the least-squares regression line? Round your answer to the nearest hundredth of a percent. QUESTION 8 Suppose you find the correlation coefficient for engineering doctorates vs cheese consumption to be approximately 0.9786. What percent of the variation in the number of engineering doctorates was explained by the least-squares regression line? Round your answer to the nearest hundredth of a percent
