Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 135 to 191 cm and weights of 37 to 150kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=167.79cm, y=81.51kg, r=0.293​, P-value=0.003​, and y=−106+1.17x. Find the best-predicted value of y (weight) given an adult male who is 147cm tall. Use a 0.10 significance level.
