An important factor in the sales of a new golf ball is how far it will travel when hit. Four different types of balls were hit by an automatic driving machine 25 times each, and their distances (in yards) were recorded. The following data, referring to the sample means and sample variances obtained with each type of ball, resulted.

Using the 5 percent level of significance, test the null hypothesis that the mean distance traveled is the same for each type of ball.
