Using the data in Ch. 13 Data Set 2 and Excel, compute the F ratio for a comparison among the three levels representing the average amount of time that swimmers practice weekly (25), with the outcome variable being their time for the 100-yard freestyle. Answer the question of whether practice time makes a difference. Don't forget to use the options feature to get the means for the groups.

(You will be using a One-Way ANOVA to determine if there is a statistically significant difference between the 3 groups of practice times)
