Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 134 to 186 cm and weights of 39 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x= 167.45 cm,y = 81.50 kg, r=0.229, P value = 0.022, and ^y^ = -101+1.04x.

Find the best predicted value of^y^ (weight) given an adult male who is 137 cm tall. Use a 0.01 significance level.

(this is my answer : -101+1.04*137 = 41.48 kg

but correct answer is 81.50kg )

I don't understand. please help me solve this problem
