If you were to develop a regression line to predict y by x, what value would the coefficient of determination have? x 213 196 184 202 221 247 y 76 65 62 68 71 75 (Do not round the intermediate values. Round your answer to 3 decimal places.) Coefficient of determination =

Step 1
Calculate the mean of x and y. Mean of x: $\bar{x} = \frac{213 + 196 + 184 + 202 + 221 + 247}{6} = \frac{1263}{6} = 210.5$ Mean of y: $\bar{y} = \frac{76 + 65 + 62 + 68 + 71 + 75}{6} = \frac{417}{6} = 69.5$ Show more…

Consider the data. The estimated regression equation for these data is y = 5 + 1.1x. What percentage of the total sum of squares can be accounted for by the estimated regression equation? (Round your answer to one decimal place.) What is the value of the coefficient of determination? (Round your answer to three decimal places.)
