2. Two-Variable Statistical
Calculations
(Ex.
1)
Calculate the mean value (x, y), standard
deviation sample
(x<rn-
1 ,
y<rn-
1 ),
correla-
tion coefficient (r), and intercept (a) and
gradient (b) at the regression line from
following weights (x) and heights
(y).
Then estimate the height
(y)
of the
people whose weights are 40 kg, and
the weight (x) of the people whose
heights are 180
em.
