Activities and Simulationsfor Day 2 & Day 3
Introduction to beads as target population1. Ex 1: Construct and compare histograms for n = 5 and n = 50
– Simulation for n = 5 and n = 50
2. Ex 2: Do hypothesis test using x-bar and introduction to alpha error– Simulation for n = 5 and n = 50
3. Ex 3: Do hypothesis test using 95% UCL – Simulation for n = 5 and n = 50
4. Ex 4: Do hypothesis test with true mean equal to LBGR, i.e., beta error– Simulation for n = 5 and n = 50
5. Ex 5a: Do hypothesis test for a very clean site– Simulation for n = 5 and n = 50
6. Ex 5b: Do test for a very dirty site– Simulation for n = 5 and n = 50
7. Other simulations and questions and answers
