When performing a 2 test for independence in a contingency table with r rows and ccolumns, determine theupper-tail critical value of the test statistic in each of the following circumstances.

a. =0.05, r=5, c=3

d. =0.01, r=3, c=5

b. =0.01, r=6, c=4

e. =0.01, r=5, c=6

c. =0.01, r=6, c=5

a. Determine theupper-tail critical value of the test statistic using the values given in the problem statement for part(a).

The critical value is

b. Determine theupper-tail critical value of the test statistic using the values given in the problem statement for part(b).

The critical value is

c. Determine theupper-tail critical value of the test statistic using the values given in the problem statement for part(c).

The critical value is

d. Determine theupper-tail critical value of the test statistic using the values given in the problem statement for part(d).

The critical value is

e. Determine theupper-tail critical value of the test statistic using the values given in the problem statement for part(e).

The critical value is
