Quiet disappointed with the end results, the manager was figuring out ways to improve the process and free the capital expenditure of $10,000. A former professor suggested going for more samples with less sample sizes. JM conducted the analysis on27 samples of 5 observations each and the results are tabulated below:

- A quality analyst wants to construct a sample mean chart for controlling a packaging process. Each day last week, he randomly selected four packages and weighed each.

One of the concerns of Mogul Motors is thatthe Eagletrons be capable of achieving appropriate maximumspeeds. To monitor this, Mogul executives take samples of eight Eagletrons at a time. For each sample, they determine the aver-age maximum speed and the range of the maximum speeds within the sample. They repeat this with 35 samples to obtain 35 samplemeans and 35 ranges. They find that the average sample mean is88.50 miles per hour, and the average range is 3.25 miles per hour.Using these results, the executives decide to establish an R chart.They would like this chart to be established so that when it showsthat the range of a sample is not within the control limits, there isonly approximately a 0.0027 probability that this is due to naturalvariation. What will be the upper control limit (UCL) and thelower control limit (LCL) in this chart?arrow_forward1. The data shown in Table 1 are x and R values for 20 samples of size n= 5 taken from a process producing bearings. The measurements are made on the inside diameter of the bearing, with only the last three decimals recorded (i.e., 31.6 should be 0.50316). Please show all your work for full credit. (a) Set up x and R charts on this process. Does the process seem to be in statistical control? If necessary, revise the trial control limits. (b) Assume that diameter is normally distributed.

- The manager of the customer service department of Data Tech Credit Card Service Company is concerned about the number of defects produced by the billing process. Every day a random sample of 250 statements was inspected for errors regarding incorrect entries involving account numbers, transactions on the customer’s account, interest charges, and penalty charges. Any statement with one or more of these errors was considered a defect. The study lasted 30 days and yielded the data in Table.
