Question: Consider the hardness testing experiment described in Section 4.1. Suppose that the experiment was conducted as described and that the following Rockwell C-scale data (coded by subtracting 40 units) obtained:
- Analyze the data from this experiment.
- Use the Fisher LSD method to make comparisons among the four tips to determine specifically which tips differ in mean hardness readings.
- Analyze the residuals from this experiment.
