Use the confidence interval technique for the process

Select one (1) project from your working or educational environment in which you would use the confidence interval technique for the process. Next, speculate on one to two (1-2) challenges of utilizing such a technique in the process and suggest your strategy to mitigate the challenges in question.  

At my current job, we use confidence interval technique for the process almost every day. We are to calculate the length of parts at the beginning and in the middle of every shift. We are checking to make sure the machine is producing accurate parts. In some areas, you will be measuring for the range, mean, or standard deviation. Once you have received either of these numbers, you will have to plot them on a graph to see if the number is in between the desired amount.

Sometimes we come across different issues. If the range, mean, or standard deviation is not between the given digits then we have a problem. Usually the engineers will fix the machine until the digits are accurate.
