alleryIf the regression coefficient of y on x is byx, then the slope of regression line y on x is
Abyx
B1/byx
C0
D-byx
Answer & Solution
Correct answer: A. byx
1. The line y on x is written as y - ymean = byx (x - xmean).
2. The coefficient of x in this equation is byx.
3. The slope of a line in this form is the coefficient of x.
4. So slope of regression y on x is byx.
