question 5

Heights(cm) and weights(kg) are measured for 100 randomly selected adultmales, and range from heights of 136 to 191 cm and weights of 39 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=168.37 cm, y=81.66 kg, r=0.332, P-value=0.001, and

y=103+1.12x. Find the best predicted value of

y (weight) given an adult male who is 170 cm tall. Use a 0.10 significance level.

The best predicted value of

y for an adult male who is 170 cm tall is ------ kg.

(Round to two decimal places asneeded.)
