a.

To determine

Obtain the 3σ control limits for R chart.

Check whether or not the variance is under control, recompute X¯¯ and R¯ by eliminating process which is not in control.

b.

To determine

Obtain the 3σ control limits for X¯ chart using sample ranges.

Check whether or not the process mean is in control, otherwise detect the sample at which the process is out of control.

c.

To determine

Check whether or not the process mean is in control, otherwise detect the sample at which the process is out of control based on Western Electric rules.

A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.34. A dietician is asked to test this claim and finds that a random sample of 16 servings has a variance of 1.22. At α=0.05​, is there enough evidence to reject the​ manufacturer's claim? Assume the population is normally distributed. Complete parts​ (a) through​ (e) below.
A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.141.14.
