The appropriate table value for a randomized block design ANOVA with 4 degrees of freedom in the numerator and 16 degrees of freedom in the denominator (calculated as (5-1) x (4-1)) at a 0.05 significance level is 3.26. Since the computed test statistic (F) of 4.35 is greater than the table value of 3.26, we reject the null hypothesis and conclude that there is a significant difference between at least two of the treatments.
