The accompanying table shows a portion of the results from conducting a two-way ANOVA test with no interaction in which five different production methods (factor A, columns) were evaluated in terms of labor cost per unit (dependent variable). Operator experience was used as a blocking factor (factor B, rows) and was considered at four levels.

a. Find the missing values in the ANOVA table. Use Excel's F.DIST.RT to find the p-values and a 5% significance level to find the critical values.
b. At the 5% significance level, can you conclude that labor cost per unit differs by production method? What about the 10% significance level?
