b. Develop the estimated regression equation that could be used to predict the percentage of

successful drilling

completions

, given the

core fracture ratio

.

1. What is the reg

ression equation? 2. What is R

-

square and what does it tell you?

3. What does the P value of the

core fracture ratio

tell us?

4

. Explain what proportion of the variable in the sample values to

the proportion of successful drilling projects does this model explain?

5

. What is the implication of this regression model to

management (the big question)?
