- mean of the process is the estimate developed in part (a). Twenty-five samples of 100 items each were inspected when a process was considered to be operating satisfactorily. In the 25 samples, a total of 135 items were found to be defective. What is an estimate of the proportion defective when the process is in control? b. a. What is the standard error of the proportion if samples of size 100 will be used for statistical process control? Compute the upper and lower control limits for the control chart.

Those volumes have a mean of 12.19 oz and a standard deviation of 0.14 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost all cans have volumes between 11.98 oz and 12.70 oz, the range rule of thumb can be used to estimate that the standard deviation should be less than 0.18 oz. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.18 oz. Use a 0.05 significance level. Complete parts (a) through (d) below. b.

The researcher who made the measurements concluded that the 8th reading 4 398 397 396 had a value of -3.625 as the "deviation from the mean" and eliminated the data 7 395 point based on the Chauvenet criterion. However, she later realized that she used the factor "1/n" instead of "1/(n-1)" in the calculation of standard deviation, which was used for data sets with a total number of data points less than 20. Find the value of the 8th reading and determine if the elimination is actually necessary. 8. ? 9 398 10 398 11 399 12 398 13 399 14 396 15 399 16 400
