Question: Augment the data by the dummy variable cooling tower as given in Table 6. Build a multiple regression model to predict ln (C) by taking

Augment the data by the dummy variable "cooling tower" as given in Table 6.

  1. Build a multiple regression model to predict ln (C) by taking S and N or their natural logarithms, as well as CT, as the independent variables. Make sure to check for multicollinearity.
  2. Use residual analysis and R2 to check your model.
  3. State which variables are important in predicting the cost of constructing an LWR plant.
  4. State a prediction equation that can be used to predict ln(C).
  5. Does adding CT improve R2? If so, by what amount?
