Another researcher is interested in the same regression, but he makes an
error when he enters the data into his regression program: He enters each
observation twice, so he has 200 observations (with observation 1 entered
twice, observation 2 entered twice, and so forth).
a. Using these 200 observations, what results will be produced by his
regression program? (Hint: Write the "incorrect" values of the sample
means, variances and covariances of Y and X as functions of the
"correct" values. Use these to determine the regression statistics.)
