QUESTION 1 Which of the following data cannot be used for estimating standard deviation of a data set? Averages of subgroups O Individual data points Standard deviations of subgroups Ranges of subgroups QUESTION 2 Which of the following is not a common component of Control Charts? Rolled Throughput Yield O Lower Control Limit O Upper Control Limit O Center Line QUESTION 3 In a control chart, when a data point falls beyond Zone A, what does it mean? O It should be in Zone B and is an alert for possible mean shift O It is just a normal event It may be a problem, depending on results of R-chart It should be a major event due to special cause QUESTION 4 Suppose we are given a data set of 25 samples with 10 data points per sample. To make an X chart of XmR, which Shewhart constant "d2" should be used? O Use d2(10) = 0.3249 O Use d2(2) = 1.128 O Use d2(10) = 3.078 O Use d2(25) = 3.931 QUESTION 1 Which of the following data cannot be used for estimating standard deviation of a data set?
