Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 136 to 187 cm and weights of 41 to 150 kg. let the predictor variable x be the first variable given. the 100 paired measurements yield x = 167 55 cm, y-81 41 kg. r-0109. p-value-0280, and y=-103 + 1.06x find the best predicted value of y (weight) given an adult male who is 170 cm tall. use a 0.01 significance level. the best predicted value of y for an adult male who is 170 cm tall is ? kg (round to two decimal places as needed.)
