Use the four methods presented in this section to determine whether there is any evidence to suggest the data are from a nonnormal population.

use the four methods describe in the lecture. Show all your work in order to get full marks for each method. Marks will be distributed as follows:

1. [3 marks] Method1 - Graphs

2. [3 marks] Method2 - Empirical Rule

3. [3 marks] Method3 - IQR/s

4. [3 marks] Method4 - Normal Probability Plot
