Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 136 to 192 cm and weights of 39 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbar equals 167.79cm, y overbar equals 81.47 kg, requals 0.113 ​, P-valueequals 0.263, and ModifyingAbove y with caret equalsnegative 107 plus 1.06x.​ Find the best predicted value of ModifyingAbove y with caret (weight) given an adult male who is 144 cm tall. Use a 0.01 significance level.
