6. (a) Suppose that n 100 i.i.d observations for (Y., X.) yield the following results where SER stands for the standard error of the regression: Ŷ 32.1+66.8X, SER=15.1, R20.81 (15.1) (12.2) 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. Using these 200 observations, what results will be produced by his program? Write it in the following format: O 9+X, SER= ,R² (-) (-) (b) Suppose that a random sample of 200 twenty-year-old-men is selected from a population and that these mens height and weight are recorded. A regression of weight on height yields Weight -99.41 +3.94 x Height. Suppose further that instead of measuring weight and height in pounds. and inches, these variables are measured in centimeters and kilograms. What are the regression estimates from this new centimeter-kilogram regression? (1 inch 2.54 cm, 1 pound-0.45 kg)
