Attempts 14. Gravetter/Wallnau Essentials - Chapter 14- End-of-chapter question 28 One set of 20 pairs of scores, X and Y values, produces a correlation of r 0.70. If SSY-150, find the standard Score: 12 Aa Aa error of estimate for the regression line. (Round your answer to two decimal places.) The standard error estimate - A second set of 20 pairs of X and Y values produces a correlation of r 0.30. If SSy estimate for the regression line.

Explanation / Answer

1)here SSE =SSy*(1-r2)=150*(1-0.72)=76.5

std error of estimate =(SSE/(n-2))1/2 =2.06

2)

here SSE =SSy*(1-r2)=150*(1-0.32)=136.5

std error of estimate =(SSE/(n-2))1/2 =2.75
