Question

Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of

137 to 193 cm and weights of 38 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield

x overbarx=167.87 ​cm, y overbary=81.46 ​kg, r=0.166​, P-value=0.099​, and y with caret = −107+1.19x.

Find the best predicted value of y with caret y ​(weight) given an adult male who is 170 cm tall. Use a 0.05 significance level.
