Question

Heights? (cm) and weights? (kg) are measured for 100 randomly selected adult? males, and range from heights of 134134 to 192192 cm and weights of 4040 to 150150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbarxequals=168.10168.10 ?cm, y overbaryequals=81.5181.51 ?kg, requals=0.2730.273?, ?P-valueequals=0.0060.006?, and ModifyingAbove y with caretyequals=negative 103?103plus+1.141.14x. Find the best predicted value of ModifyingAbove y with carety ?(weight) given an adult male who is 188188 cm tall. Use a 0.100.10 significance level. The best predicted value of ModifyingAbove y with carety for an adult male who is 188188 cm tall is ??? kg.

Explanation / Answer

The regression equation is

Y=-103+1.14X

Then the best predicted value of modifying above y with variety for an adult who is 188188 cm tall is?

That is X=188188

Y=-103+1.14*188188

Y=214533 kg
