Mr. WMI is given the following regression equation:

% Sales Growth = b0 + b1 GDP

% Sales Growth = 6,253 + 0.7 GDP

Where:

(Standard deviation b0) Sb0 = 1.78

(Standard deviation b1) Sb1 = 0.21

(Standard Error of Estimate) SEE = 2.79

At the 95% confidence level, it is estimated that the population regression coefficients will be at intervals

A. -0.51 until 2.14

B. 0.35 until 1.05

C. 0.61 until 0.84

D. 0.28 until 1.12.
