Mastering Simple Linear Regression

b1-1s{b1}~t(n-2)

b1t(1-2;n-2)s{b1}

b1=Y-b1X

b1=(Xi-X)(Yi-Y)(Xi-X)2=SSXYSSX (correct)

The variance of the “residuals”

The estimated variance of the “residuals” (correct)

The standard error of the “residuals”

The mean of the “residuals”

Margin Error = t * Standard Error * s2

Margin Error = t * Standard Error + s2

Margin Error = t * Standard Error (correct)

Margin Error = t * Standard Error / s2
