Question
Plating of gold on wrist watches requires a chemical called AiCI3. Concentration of the chemical that is added to the solution is an important factor. The objective is to choose that concentration for which plating is uniform. Three concentration of AiCI3 chosen were 5%, 15% and 20%. These were added in the solution and plating was done and thickness (in units) measured on 5 samples is gives below.
| Conc. of AiCI3 /Sample | 1 | 2 | 3 | 4 | 5 | |
| 5% | 3 | 2 | 4 | 2 | 4 | |
| 15% | 4 | 4 | 3 | 2 | 4 | |
| 25% | 3 | 3 | 4 | 4 | 2 | |
Use ANOVA to comment on whether the concentration of AiCI, gives same result or not. (Use =0.05)
