Sample Size for Kendall Tau and Chi Square

#1
Looking for help determining sample size for kendtall tau and chi square. Research has sample of 108, need to justify it. Familiar with formula in
Bonett, D. G., & Wright, T. A. (2000). Sample size requirements for estimating Pearson, Kendall and Spearman correlations. Psychometrika, 65(1), 23-28.

Would appreciate someone helping me run the formula, not sure the mean, variance and confidence interval since its ranked data.
