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

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.

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...
