Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 138 to 187 cm and weights of 40 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=167.94 cm, y=81.54 kg, r=0.261​, P value=0.009​, and y=−102+1.03x. Find the best predicted value of y ​(weight) given an adult male who is 181 cm tall. Use a 0.10 significance level.
