Suppose a doctor measures the height, x, and head circumference, y, of 11 children and obtains the data below. The correlation coefficient is 0.857 and the least squares regression line is y = 0.168x + 12.836. Complete parts (a) and (b) below. Height, x 27.25 25.5 26.5 25.25 28 26.5 25.75 27 27.25 27.25 27 Head Circumference, y 17.6 17.2 17.2 17.0 17.5 17.4 17.2 17.3 17.4 17.4 17.4 (a) Compute the coefficient of determination, R2 R2 =% (Round to one decimal place as needed.) (b) Interpret the coefficient of determination. Approximately % of the variation in is explained by the least-squares regression model. (Round to one decimal place as needed.)
