what is C

c.) Is the test statistic in the rejection region? How do you know?

The contingency table shows the results of a random sample of high school students with respect to year and grade point average. At the significance level, a-0.05, test the claim that at least two of the variables are dependent. Use the Independence #2 calculator to test the hypothesis. Fill in the contingency table for row and columns based on the results. Also fill in the space for the level of significance a H O: The variables are independent H a: At least two of the variables are dependent (claim) a.) Find the degrees of freedom, the critical value and identify the rejection region. b.) Find the chi-square test statistic c.) Is the test statistic in the rejection region? How do you know? d.) Do we reject or fail to reject the null hypothesis? e.) Is there enough evidence to support the claim that at least two of the variables are dependent? Give a full conclusion statement including the level of significance.
