A regression line using 25 observations produced SSR = 118.68 and SSE = 56.32. The standard error of estimate was:
A)2.1788.
B)1.5648.
C)1.5009.
D)2.2716.

The standard error of the estimate can be calculated using the formula: sqrt(SSE / (n - 2)), where SSE is the sum of squares due to error, and n is the number of observations. Plugging in the given values, we get sqrt(56.32 / (25 - 2)) = sqrt(56.32 / 23) = 1.5648.
