Please use Excel QM to solve this problem. The data can be pasted into the spreadsheet. You do not

have to do any calculations.

Small boxes of NutraFlakes 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 $19\mathrm{.}810\mathrm{.}19\mathrm{.}99\mathrm{.}79\mathrm{.}7$

Box $210\mathrm{.}410\mathrm{.}210\mathrm{.}59\mathrm{.}810\mathrm{.}1$

Box $39\mathrm{.}99\mathrm{.}910\mathrm{.}310\mathrm{.}39\mathrm{.}9$

Box $410\mathrm{.}39\mathrm{.}810\mathrm{.}110\mathrm{.}29\mathrm{.}9$

Using these 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?
