Question

Dependent variable - Machine maintenance costs

Independent variable - Machine hours

Intercept - 3500

Coefficient on independent variable - 3.50

Coefficient of correlation - 0.856

R^2 - 0.733

What percentage of the variation in maintenance costs is explained by the independent variable?

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
