Facts About the F Distribution · Exercise 16

A video game developer is testing a new game on three different groups. Each group represents a different target market for the game. The developer collects scores from a random sample from each group. The results are shown in.
$$\begin{array}{ccc}\text{Group A}& \text{Group B}& \text{Group C}\\ \text{101}& \text{151}& \text{101}\\ \text{108}& \text{149}& \text{109}\\ \text{98}& \text{160}& \text{198}\\ \text{107}& \text{112}& \text{186}\\ \text{111}& \text{126}& \text{160}\end{array}$$

At the 10 percent significance level, are the scores among the different groups different?
