1. Use a χ2 test to
test the claim that in the given contingency table, the row
variable and the column variable are independent.
Responses to a survey question are broken down according to
employment status and the sample results are given below. At the
0.10 significance level, test the claim that response and
employment status are independent.
a. find the test statistic
2. Use a χ2 test to
test the claim that in the given contingency table, the row
variable and the column variable are independent.
Tests for adverse reactions to a new drug yielded the results given
in the table. At the 0.05 significance level, test the claim that
the treatment (drug or placebo) is independent of the reaction
(whether or not headaches were experienced).

Use a χ2 test to test the claim that in the given contingency table, the row variable and the column variable are independent. 160 students who were majoring in either math or English were asked a test question, and the researcher recorded whether they answered the question correctly. The sample results are given below. At the 0.10 significance level, test the claim that response and major are independent. a. test statistic b. critical value
