QuestionHeights ( cm ) and weights ( kg ) are measured for 100 randomly selected adult males, and range from heights of 139 to 193 cm and weights of 38 to 150 kg . Let the predictor variable x be the first variable given. The 100 paired measurements yield xˉ=167.54 cm,yˉ=81.44 kg,r=0.185,P\bar{x}=167.54 \mathrm{~cm}, \bar{y}=81.44 \mathrm{~kg}, \mathrm{r}=0.185, P-value =0.065=0.065, and y^=107+1.05x\hat{y}=-107+1.05 x. Find the best predicted value of y^\hat{y} (weight) given an adult male who is 161 cm tall. Use a 0.05 significance level.
