The Friedman test would be appropriate in this case as it is a non-parametric test used to analyze differences among three or more related groups. It allows for the comparison of three or more groups, in this case three business plans, with repeated measures. It tests whether there is a significant difference in the rank ordering of the three groups across the repeated measures. Therefore, the Friedman test is the best choice in this scenario.
