Question

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 133133 to 190190 cm and weights of 3737 to 150150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbarxequals=168.08168.08

cm, y overbaryequals=81.5781.57 kg,

requals=0.3130.313, P-valueequals=0.0020.002,

and ModifyingAbove y with caretyequals=negative 108−108plus+1.121.12x.

Find the best predicted value of ModifyingAbove y with carety

(weight) given an adult male who is 169169

cm tall. Use a 0.050.05 significance level.

The best predicted value of ModifyingAbove y with carety for an adult male who is

169169 cm tall is (answer) kg. (Round to two decimal places as needed.)
