When performing an x^2 test for 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=3, c=4

B) a= 0.01, r=6, c=3

C) a=0.01, r=6, c=4

D) a=0.01, r=3, c=4

E) a=0.01, r=5, c=6

Determine the upper-tail critical value of the test statistic using the values given in the problem statement for parts (a) through (e)

**Round answers to three decimal places as needed!**

The critical value for (A)-

The critical value for (B)-

The critical value for (C)-

The critical value for (D)-

The critical value for (E)-
