Exhibit 13-4
In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations). The following information is provided.
SSTR = 200 (Sum Square Between Treatments)
SST = 800 (Total Sum Square)
-Refer to Exhibit 13-4. If at 95% confidence we want to determine whether or not the means of the five populations are equal, the p-value is
A)between 0.05 to 0.10
B)between 0.025 to 0.05
C)between 0.01 to 0.025
D)less than 0.01

The p-value is less than 0.01 because the F-statistic is 200/40 = 5, and the critical value of F with 4 and 60 degrees of freedom at 95% confidence is 2.54.
