Answer 1

Answer:

c. both x-bar chart and r-chart.

Explanation:

When Jars of pickles are sampled and weighed, sample measures are plotted on control charts and the ideal weight should be precisely 11 oz.

Both x-bar chart and r-chart can be used to monitor the process.

The x-bar and r-chart in statistical process monitoring (spm) are quality control charts used to monitor the process mean and process variation simultaneously, based on samples collected in subgroups in a given time.
