Answer the following questions for data set of nested design:
1. Write the linear model and source ANOVA table for the nested design in symbolic notation. The
ANOVA table should include the variance sources, degree of freedom and expected

1. Describe the trend in the scatter plot of the raw data: what is the relationship between variables
EX and MET?
The trend in the scatter plot shows some curves, so it is not linear. Therefore, we fit a polynomial
