A human resource specialist wants to determine whether the average job satisfaction score (on a scale of 0 to 100) is the same for three different industries and three types of work experience. A randomized block experiment with interaction is performed. The results are shown in the accompanying table.

a. Use Excel to generate the appropriate ANOVA table at the 5% significance level.
b. At the 5% significance level, is there interaction between industry and work experience?
c. At the 5% significance level, can you conclude that job satisfaction differs by industry?
d. At the 5% significance level, can you conclude that job satisfaction differs by work experience?
