In a poll, 360 students were tested about their interests in mathematics and statistics, the results are presented in the table below. Please determine at 0.01 level of significance whether a student’s interest in mathematics and independent of his/her interest in statistics.

Interest in statistics		Interest in mathematics
		Low	Average	High
	Low	63	42	15
	Average	58	61	31
	High	14	47	29

In this scenario which chi-square test does he need to perform?
Please construct the null and alternative hypotheses, and specify the type of test it is (e.g., two-sided, left or right sided test)
Please compute the expected counts for each cell of the contingency table
Please compute the test statistics.
Please determine the degree of freedom, and then compute the p-value (you are using p-value approach for this task)
Please state your conclusions.

Can a pretest on mathematics skills predict success in a statistics course? The 82 students in an introductory statistics class took a pretest at the beginning of the semester. The least-squares regression line for predicting the score y on the final exam from the pretest score x was ŷ = 9.6 + 0.77x. The standard error of b1 was 0.44 (a) Test the null hypothesis that there is no linear relationship between the pretest score and the score on the...
