A researcher has regressed y on x using a random sample and obtained an estimated model. However, they find that the units for variables x and y are $100 and $1000, respectively. To avoid confusion, he decides to scale the variables (and the data) to make x and y both have $1 as their units, and then re-run the estimation with the modified data. Which one of the following statements about the new estimation results is correct?

a) R2 will not change.

b)Estimated slope coefficient will be 1

c)Estimated intercept term will be 1.

d)The SE of the estimated slope coefficient will be 1.
