What is the idea behind the chi-square test for independence? Select one: a. to compare the quantile-quantile (Q-Q) plot with what would be expected under independence b. to compare the actual counts in a contingency table with what would be expected under independence c. to compare the cumulative distribution with what would be expected under independence d. none of these choices

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...

59. A chi-square test of independence with 10 degrees of freedom results in a test statistic of 19.25. Using the chi-square table, which of the following is the most accurate statement that can be made about the p-value for this test? A: p-value < 0.025 B: 0.05 < p-value < 0.10 C: 0.10 < p-value < 0.20 D: 0.025 < p-value < 0.05
