versus the X's as follows. Start with an equation that has all of
the X's. Then if any X has a p-value greater than 0.10, run another
regression without the variable that has the largest p-value. Keep
running regressions, always deleting the variable with the largest
p-value, until all of the remaining p-values are less than 0.10.
Which of the following is true? Click here to reference the data
needed to answer the question. a. The final equation has a standard
error of estimate greater than the standard error of estimate for
the equation with all of the X's, but the difference is less than
0.10. b. The final equation has an R-square value greater than the
R-square value for the equation with all of the X's, but the
difference is less than 0.001. c. The final equation contains 6 of
the 8 X's, and the two variables missing both have a correlation
less than 0.10 (in magnitude) with Y. d. None of these choices are
true.
