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 question correctly.

I need help with this problem. Chi-Square Test A researcher is interested in determining whether an association exists between successful campaign fund raising and political success in elections. The following cross- tabulation displays the data she collected about the amount raised (characterized as either High/Low) and overall political success (coded as Successful/Not Successful). Calculate the chi-square and interpret your results. Assume an alpha = .05. Fund Raising Political Success Low High Totals Not Successful 24 6 30 Successful 8 22...
