a. Calculate the mean, standard deviation, and the coefficient of
variation of the data.
b. Using a spreadsheet program, create a control chart for these data
showing the target value and the lower specification limit. Is the
plant production meeting the specification requirement? If not,
comment on possible reasons. Comment on the data scatter.
