# Confidence Intervals and Control Limits

The operation time is calculated for scenarios one and two. The point of the exercise is to identify the scenario that takes the least amount of time ie... the time difference between the two scenarios.

Explain the control limits (see word .doc) and calculate them upper and lower limits. Calculate confidence intervals and explain them per the data sets given.
