Help of in lb) from 40 randomly selected men. The inear correlation coefficient

Question

Help of in lb) from 40 randomly selected men. The inear correlation coefficient r is 0.483. Find the value of the Assume that you have paired values consisting of heights (in inches) and weights practical information does the coefficient of determination provide? e coefficient of determination is 0 767 233% of the variation is explained by the linear correlation, and 76 7% is explained by other factors The coefficient of determination is 0.233 233% of the variation is explained by the linear correlation and 76 7% is explained by other facts The coefficient of determination is 0.233 76 7% of the variation is explained by the linear correlati a d 23 3% is explained by other factors 76 7% of the variation is explained by the linear correlation, and 23 3% is explained by other factors Choose the correct answer below O B O D. The coefficient of determination is 0 767

Explanation / Answer

Coefficient of determination is given by r-square
r = coefficient of correlation

Hence, coefficient of determination = (0.483)^2 = 0.233289

This means the linear correlation explains 23.33% of variation

Hence option B is correct
