A data analyst is conducting a study to determine if the mean number of courses taken in a college semester is
statistically the same between freshmen, sophomores, juniors, and seniors. A sample of four students is selected from each grade level, and the number of courses each student is taking currently is recorded. Assume that the conditions for a one-way ANOVA are met. Determine the critical value for this one-way ANOVA test using a 5% significance level based on the table of critical values of the F-distribution shown below.
what is the critical value?
