Answer #1

Solution: We need to complete the ANOVA table, in order to find the test statistic that is used to determine if there is a relationship among the variable.

The ANOVA can be filled as:

We are given there are 20 observations in the sample. Also we are given the number of predictor variables is 2.

Therefore, we have:

Therefore, the test statistic used to determine if there is relationship among the variables equals
