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

136

to

192

cm and weights of

40

to

150

kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield

x=167.41

cm,

y=81.42

kg,

r=0.196,

P-value=0.051,

and

y=103+1.06x.

Find the best predicted value of

y

(weight) given an adult male who is

177

cm tall. Use a

0.10

significance level.
