Cartons of Plaster of Paris are supposed to weigh exactly 32 oz. Inspectors want to develop process control charts. They take 5 samples of 6 boxes per sample and weigh them. Based on the following data, what are the lower and upper control limits for the 3-sigma mean chart and the range chart, respectively? Please keep two decimal places and select the best answers.

 

Select one:
a.

[33.8, 34.76], [0, 2.00]

b.

[33.96, 34.60], [0, 1.18]

c.

[34.01, 34.55], [0, 1.12]

d.

[34.01, 34.55], [0.52, 2.52]

e.

[32.6, 35.96], [0, 1.12]

The table presented provides a summary of statistical data across five different samples. It includes three columns: "Sample," "Mean," and "Range." - **Sample**: This column numbers the samples from 1 to 5. - **Mean**: This column lists the average value for each sample. The mean values are 33.8, 34.6, 34.7, 34.1, and 34.2, corresponding to samples 1 through 5, respectively. - **Range**: This column shows the range, which is the difference between the highest and lowest values in each sample. The range values are 1.1, 0.3, 0.4, 0.7, and 0.3 for samples 1 to 5, respectively. This table is useful for understanding the central tendency and variability of the different samples in the dataset.
