Please use Excel QM to solve this problem. The data is pasted into the spreadsheet. You do not have to do any calculations. 

Small boxes of Nutra Flakes cereal are labeled "net weight 10 ounces." Each hour, random samples of size boxes are weighed to check process control. five hours of observations yielded the following: 

Time   9.a.m    10.a.m    11.a.m     Noon     1.p.m 

Box 1   9.8         10.1         9.9          9.7        9.7 

Box 2    10.4      10.2        10.5         9.8       10.1 

Box 3     9.9         9.9         10.3       10.3      9.9 

Box 4     10.3       9.8         10.1        10.2        9.9 

Using the data, construct limits for x-bar and R-charts. is the process in control?

What other steps should the quality control department follow at this point?
