When performing a chi squaredχ2 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.
b. alpha = 0.01, r = 5, c = 3
c. alpha = 0.01, r = 5, c = 4
d. alpha = 0.01, r = 3, c = 4
e. alpha = 0.01, r = 4, c = 5
QUESTION: what are the critical values for b,c,d,e?
Part b
We are given
Degrees of freedom = df = (r – 1)*(c – 1) = (5 - 1)*(3 - 1) = 4*2 = 8
α = 0.01
Critical value = 20.09024
(by using Chi square table or excel)
Part c
We are given
Degrees of freedom = df = (r – 1)*(c – 1) = (5 - 1)*(4 - 1) = 4*3 = 12
α = 0.01
Critical value = 26.21697
(by using Chi square table or excel)
Part d
We are given
Degrees of freedom = df = (r – 1)*(c – 1) = (3 - 1)*(4 - 1) = 2*3 = 6
α = 0.01
Critical value = 16.81189
(by using Chi square table or excel)
Part e
We are given
Degrees of freedom = df = (r – 1)*(c – 1) = (4 - 1)*(5 - 1) = 3*4 = 12
α = 0.01
Critical value = 26.21697
(by using Chi square table or excel)

this is the table given Perform a chi-square independence test using the critical value approach, provided the conditions for using the test are met. Be sure to state the hypotheses and the significance level, to obtain the expected frequencies, to obtain the critical value, to compute the value of the test statistic, and to state your conclusion. 160 students who were majoring in either math or English were asked a test question, and the researcher recorded whether they answered the...
