Question 315034
The average of the data is 8.282 with a standard deviation of 0.301. 
The upper acceptable limit is 8.2.
The lower acceptable limi is 7.8.
This process is badly out of control. 
Not only is the average above the upper limit but the spread of the data is too wide. 
You would want the (Ave-3*sigma, A+3*sigma) to be contained within the (7.8-8.2) allowable range. 
With this process, (Ave-3*sigma, A+3*sigma)=(7.4-9.2) nowhere near the current allowable limits.
Stop this process and fix whatever is broken.
