Heights​ (cm) and weights​ (kg) are measured for 100randomly selected adult​ males, and range from heights of
134
to
192
cm and weights of
38
to
150
kg. Let the predictor variable x be the first variable given.The 100 paired measurements yield
x=167.11
​cm,
y=81.29
​kg,
r=0.216​,
​P-value=0.031​,
and
y=−103+1.16x.
Find the best predicted value of
y
​(weight) given an adult male who is
157
cm tall. Use a
0.05
significance level.
