Suppose that a random sample of 200 twenty-year-old men is selected from a population and that these men’s height and weight are recorded. A regression of weight on height yields

Regression Line

The task is: Suppose 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 and 1 pound = 0.4536 kg) (Give all results, estimated coefficients, R2 , and SER.)

    $r$ and $r^2$ (sometimes denoted in regression printouts as `R2` or `R-sq`) will not change because $r$ is a dimensionless quantity. – 2017-02-19

    Yes! I understand that R2 isn't changing, but what about the other coefficients? – 2017-02-19
