Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 131131 to 194194 cm and weights of 4141 to 150150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbarxequals=167.50167.50 ​cm, y overbaryequals=81.4381.43 ​kg, requals=0.4180.418​, ​P-valueequals=0.0000.000​, and ModifyingAbove y with caretyequals=negative 105−105plus+1.191.19x. Find the best predicted value of ModifyingAbove y with carety ​(weight) given an adult male who is 150150 cm tall. Use a 0.100.10 significance level. The best predicted value of ModifyingAbove y with carety for an adult male who is 150150 cm tall is nothing kg. ​(Round to two decimal places as​ needed.)
