# Simple Regression

Simple Regression. The European Engine Company (EEC) is a multi-national manufacturer of small gasoline and diesel motors. EEC has estimated the following cost experience for a new 3.5 hp engine over a sample of 122 observations:

COST = $8,500 + $32 OUTPUT

Predictor Coef Stdev t ratio

Constant 8,500 5,000 1.7

OUTPUT 32 8 4.0

SEE = $2,500 R2 = 75% = 74.8% F statistic = 360

where COST is the dependent Y variable and OUTPUT is the independent X-variable.

A. Fully interpret these simple regression results.

B. Describe this cost category as fixed or variable based upon the simple regression results described previously
