After Sandy Smith, the bakery owner, read the report with your vision of the monitoring system to improve the service to the customers of their small family$-$owned bakery, she met with you to decide what process variables could be used to start monitoring the bakery processes performance. The owner and you initially decided to monitor the following variables:

Oven Temperature in degrees Fahrenheit $(\backslash$deg F$)$

Number of units produced daily

Number of defective units produced daily

The owner provides you data that the bakery has collected on these variables during the past months.
