Assume that in Example 36.3 the number of samples was 8 instead of 10. Using the top half of the data in Table 36.4, recalculate the control limits and the standard deviation. Compare your observations with the results obtained by using 10 sample
Example 36.3
The data given in Table 36.4 show length measurements (mm) taken on a machined workpiece. The sample size is 5, and the number of samples is 10; thus, the total number of parts measured is 50. The quantity x is the average of five measurements in each sample. Determine the upper and lower control limits and the standard deviation for the population of machined parts.
