When performing a x2 test of independence in a contingency table with r rows and c columns, determine the upper-tail critical value of the test statistic in each of the following circumstances:

a. a = 0.05, r = 4 rows, c = 5 columns

b. a = 0.01, r = 4 rows, c = 5 columns

c. a = 0.01, r = 4 rows, c = 6 columns

d. a = 0.01, r = 3 rows, c = 6 columns

e. a = 0.01, r = 6 rows, c = 3 columns
