Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 132 to 191 cm and weights of 38 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=167.41 ​cm, y=81.44 ​kg, r=0.231​, ​P-value=0.021​, and y=−105+1.12x. Find the best predicted value of y ​(weight) given an adult male who is 180 cm tall. Use a 0.01 significance level.

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

132

to

191

cm and weights of

38

to

150

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

x=167.41

​cm,

y=81.44

​kg,

r=0.231​,
​P-value=0.021​,

and

y=−105+1.12x.

Find the best predicted value of

y

​(weight) given an adult male who is

180

cm tall. Use a

0.01

significance level.
