Johnson Filtration, Inc. provides maintenance service for water-filtration systems. Data that follow show the repair time in hours, the months since last service, the repair type and the repair person for a sample of 10 maintenance service calls.

Ignore the months since last service and the repairperson data. Let type of repair be a dummy variable with 0 indicating a mechanical repair and 1 indicating an electrical repair. Develop the estimated simple linear regression equation that can be used to predict the repair time based on the type of repair (to 3 decimals).
Time = (3.45) + (.617) Type

Is type of repair a good predictor of the repair time?

Ignore the months since last service and the type of repair data. Let repairperson be a dummy variable with 0 indicating Bob Jones and 1 indicating Dave Newton. Develop the estimated simple linear regression equation that can be used to predict the repair time based on the repairperson (to 2 decimals).
Time = 4.62 + (Answer) Person

Compare your results from parts (a) and (c). What can you conclude?

Repairperson is a better predictor
