J. McWilliams Swim Club is trying to calibrate their chlorine pump to ensure that the right amount of chlorine (1.0-1.5 ppm of free chlorine) is mixed into the water. Thirty samples of four readings at random times during the week were taken. These data can be found in the Problem 14 dataset. Compute the mean and range of each sample and calculate control limits for x-bar and R charts using the appropriate formulas. Based on the mean and range chart, does the process appear to be 2023 in statistical control?) ques J.
