Question

Sixty-four students in an introductory college economics class were asked how many credits they had earned in college, and how certain they were about their choice of major. At α = .01, is the degree of certainty independent of credits earned?

Credits Earned	Very   Uncertain	Somewhat   Certain	Very Certain	Row Total
0 – 9	11	10	3	24
10 – 59	10	5	9	24
60 or more	2	9	11	22

(a) At α = .01, the hypothesis for the given issue is H₀: Credits Earned and Certainty of Major are independent.

	Yes
	No

(b) Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Round your test statistic value to 2 decimal places and the p-value to 4 decimal places.)
