The
regression equation between Y equals fuel efficiency and PGX equals
horsepower for a random sample of contact cars was found to be
white cab eagles 44.0-0.15 X the coefficient of determination for
the model was R squared equals .72
a)
write a sentence interpreting the value of our two in terms of
variables in the model be a specific as possible
b)
find the correlation coefficient are between fill efficiency and
horsepower
c)
is the intercept meaningful in this model? explain what a value of
us and her sept here or is likely an example of extrapolation
d)
your friend Jesse drives a Ford F150 pick up a 375 hp he ask you
whether he should use this model to predict his fuel-efficiency?
what would you advise Jesse and why
