LabCorp has implemented a system to reduce the number of errors (false positives and false negatives) in its blood tests for its facilities located in Texas. The table below depicts the number of errors per month for 15 months based on data from a sample of 6 locations. LabCorp wants to assess whether those locations are capable of meeting the specification limits of LSL = 0 false positives and false negatives per month and USL = 50 false positives and false negatives per month. Show all calculations in detail.

1. Determine whether the process of testing the blood samples is in control or not.
2. Determine if those facilities were able to meet the LSL and USL requirements.
3. Calculate the percentage of locations that do not meet the specification limits
