Suppose that n = 50, i.i.d observations for (Y₁, X₁) yield the following regressions results: Ỹ= 49.2 + 73.9 X, SER (23.5) (16.4) = 13.4, R²=0.78 Another researcher is interested in the same regression, but makes an error when entering the data into a regression program: The research enters each observation twice, ending up with 100 observations (with observation 1 entered twice, observation 2 entered twice and so forth). Using these 100 observations, what results will be produced by the regression program? Complete the spaces in the equation below. Report the intercept and slope to one decimal place, but report the R2 to two decimal places. Ŷ= + *X, R² =

Question
Transcribed Image Text:Suppose that n = 50, i.i.d observations for (Y₁, X₁) yield the following regressions
results:
Ỹ= 49.2 + 73.9 X, SER = 13.4, R²=0.78
(23.5) (16.4)
Another researcher is interested in the same regression, but makes an error when
entering the data into a regression program: The research enters each observation
twice, ending up with 100 observations (with observation 1 entered twice, observation
2 entered twice and so forth).
Using these 100 observations, what results will be produced by the regression
program? Complete the spaces in the equation below. Report the intercept and slope
to one decimal place, but report the R2 to two decimal places.
Ŷ = +
