The authors of the paper "Weight-Bearing Activity during Youth Is a More Important Factor for Peak Bone Mass than CalciumIntake" studied a number of variables they thought might be related to bone mineral density (BMD). The accompanying data onx = weight at age 13 and y = bone mineral density at age 27 are consistent with summary quantities for women given in thepaper.Weight (kg) BMD (g/cm²)54.41.1559.31.2674.61.4262.01.0673.71.4470.81.0266.81.2666.71.3564.71.0271.80.9169.71.2864.71.1762.11.1268.51.2458.31.00A simple linear regression model was used to describe the relationship between weight at age 13 and BMD at age 27. Thefollowing values are given for this data.a = 0.5584SSTO= 0.356n = 15b = 0.0094SSResid= 0.31290(a) What percentage of observed variation in BMD at age 27 can be explained by the simple linear regression model? (Roundyour answer to two decimal places.)%(b) Give an estimate of o. (Round your answer to five decimal places.)Interpret this estimate.This is an average of weight values in the sample from the value predicted by the least-squares line.O This is a typical deviation of a weight value in the sample from the value predicted by the least-squares line.This is an average of bone mineral density values in the sample from the value predicted by the least-squares line.O This is a typical deviation of a bone mineral density value in the sample from the value predicted by the least-squaresline.(c) Give an estimate of the average change in BMD associated with a 1 kg increase in weight at age 13.
