Q2. Factory A produces 100 pieces of wooden legs used in manufacturing tables in 1 hour. The factory in total works for 3 hours. The quality manager decided to check the quality of the output by measuring the length of the legs (in cms). He decides to collect three samples (one for each hour). The sample size for each sample is fixed at 5. The data collected is present in the following table: Leg 1 Leg 2 Leg 3 Leg 4 Leg 5 Sample 1 10.2 10.5 9.8 9.7 10.3 Sample 2 10.4 9.9 10.1 10.2 9.8 Sample 3 9.9 9.8 10.2 10.1 10.4 What is the mean and range of leg length in sample 1?

1. Mean=10.3;Range=.3
