1 way ANOVA analysis was used to test the effectiveness of 3 kinds of headache medicines (Advil, Tylenol, and Excedrin). The analysis involved 21 people (7 per group), and used an alpha level of 0.01. What is the Critical Value

The critical region is F >F ₀.₀₁ (2,18) = 6.01

Step-by-step explanation:

For 1 way ANOVA the degrees of freedom Between Samples would 2 and within Samples would be 18 .

Alpha is given  to be = 0.01

v1 = k-1 and v2 = n-k

Where k is the number of rows and n is the total number of values

v1= 3-1= 2   and v2 = 21-3= 18

So if we look up the table we find the values of the critical region to be 6.01

Hence the critical region is less and equal to 6.01

The critical region is F >F ₀.₀₁ (2,18) = 6.01
