The mean for skinfold fat (hydrostatically determined) is 25% and the standard deviation is 10%. The coefcth of determination for skinfold fat and hydrostatically determined body fat is .91. Assume that the prediction equation for predicting hydrostatically determined percent fat from skinfolds is percent fat' = skinfolds X 0.5 + 2. 10. Calculate Terry's estimated hydrostatically determined percent fat if Terry's skinfold thickness is 20 mm. 11. Calculate the error for predicting percent fat from skinfolds. 12. How likely is it that Terry udll have an actual percent fat greater than 14 if Terry's skinfold thickness is 20 mm?I The answer is a probability (ie.= a number). Answer items 13 to 15 from the following information: Professor Dunn is interested in predicting class success on the final examination 'om scores on the midterm examination. He notes that the correlation between the midterm and nal is .80 {a high correlation). Assume that the tests had the following characteristics: mean of midterm = 100; mean of nal = 200; s ofmidtenn =10;s of nal =100;r = .80. 13. Calculate the standard error of estimate. 14. The equation for predicting final examination scores from midterm scores is dened as 'i.' = 3 X X + 10. Terry scored 40 on the midterm. What is Terry's predicted score on the final
