(a) How many treatments are there?
(b) What is the total sample size?
(d) From the information given above, fill in the blanks in ANOVA table below. Calculate the value of F also. (Round the values to the nearest whole number.)

Treatment 2
Error 20
Total 500 11
(c) What is the critical value of F? (Round your answer to 2 decimal places.) .

(a) 2+1=3
(b)500+1=501
(c)the critical value of F is F(0.95, df1=2, df2=20) =3.49 (check F table)
(d) H0: mu1=mu2=mu3 (null hypothesis)
Ha: at least one of the means is different. (alternative hypothesis)
(e)We reject the null hypothesis. The means are not all equal. At least one is different.
