10 mins: Discussion and Summary
1. In a process, 20 samples of size 10 are taken. The standard deviation of each sample is calculated. Construct X̄ and S charts and interpret the results.
2. A textile mill records the weight of fabric rolls in 15 samples of size 6. The mean and standard deviation for each sample are noted. Prepare X̄ and S charts.
