Data was collected from manufacturing plant to study several factors affecting labor production. These factors are:

• Training Hours of each Labor,
• Labor Age,
• Weather Temperature,
• Labor Years of Experience,
• Shift Number.

Use the Labor Production Data Sheet to perform the following tasks:

1. Develop a mathematical equation to predict the labor production using all factors.
2. Provide your comments on the prediction accuracy of the previous equation.
3. Develop a mathematical equation to predict the labor production using two factors only.
4. Provide your comments on the prediction accuracy of the previous equation.
