Heights? (cm) and weights? (kg) are measured for 100 randomly selected adult? males, and range from heights of 137 to 191 cm and weights of 40 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbar =167.55 ?cm, y overbar =81.35 ?kg, r =0.153?, ?P-value =0.129?, and Y hat = -107 + 1.17x. Find the best predicted value of y hat (weight) given an adult male who is 169 cm tall. Use a 0.05 significance level.

The answer I came up with was y Hat= -107 + 1.17 * 169 = 90.73kg . I can't figure out what i'm doing wrong ?(Round to two decimal places as? needed.)
