Use the following ANOVA table for regression to answer the questions.

Analysis of Variance

Give the F-statistic and p-value.

It is given that

Mean sum of square of error is MSE = 154.9

The pooled standard deviation can be calculated as

Pooled SD = √(MSE) = √(154.9) = 12.45 (upto 2 decimal places)

From the given ANOVA table, the F-statistic is given by

F = 1.85

From the given ANOVA table the p-value is given by

P-value = 0.176
