Question 30
The regression equation
Y=3,698+2,538x
gives an
R2
value of 0.2645 . This means that
?
x
and
Y
have a very high level of correlation
the percentage of variation in
Y
that is attributed to random factors is
26.45%
26.45%
of the varistion in
Y
can be explained by
x
a one-percent change in
r
will lead to a
26.45%
charge in
x
