Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 134 to 190 cm and weights of 38 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x = 167.72 cm, y = 81.47 kg, r= 0.374, P-value = 0.000, and y = - 103 + 1.07x. Find the best predicted value of y (weight) given an adult male who is 157 cm tall. Use a 0.10 significance level. The best predicted value of y for an adult male who is 157 cm tall is kg. (Round to two decimal places as needed.)
