Make an average$-$range chart for the data shown in Fig. $3\mathrm{.}2($excluding UCL and LCL values$).$ For

calculations in this exercise, you may round all values to the second decimal place.

Note for Exercise $3\mathrm{.}1$: You can do this exercise using some spreadsheet software such as MS Excel if you

choose to do so$.$ However, it is preferred that you do this exercise on a hard copy sheet with a pencil

and a non$-$smart scientific calculator. $-$R charts are very commonly used in a factory environment. To

this day of the computer era, they are still often filled manually on clipboards in manufacturing cells.
