We have no prior information, other than the 5 samples (where each sample has 4 observations) Number 1 2 3 4 Sample 1 0.5014 0.5022 0.5009 0.5027 Sample 2 0.5021 0.5041 0.5032 0.5020 Sample 3 0.5018 0.5026 0.5035 0.5023 Sample 4 0.5008 0.5034 0.5024 0.5015 Sample 5 0.5041 0.5056 0.5034 0.5039 1. Compute the sample range and mean for each of the 5 samples. 2. Compute , the average of the sample means, and R. the average of the sample ranges. 3. Construct the X-chart to check if the sample mean is in control 4. Construct the Range chart to check if process variation is in control
