Q16: The Excel file STATISTICSSTUDENTSSURVEYFORR contains the column MOTHDEGREE (a categorical variable that indicates the degree obtained (or being obtained) by a student's mother (GraduateProfessional, HighSchool, Undergraduate) and the column JTGOOD (a categorical variable that indicates whether a student believes Justin Trudeau's job performance is good (no, yes). We consider, somewhat artificially, the Statistics 151 student data in the STATISTICSSTUDENTSSURVEYFORR file to be a random sample from a much larger hypothetical population of Canadian students. Using a level of significance of 5%, use R/Rcmdr to perform a test of independence to determine if mother's final degree and student opinion about Justin Trudeau's job performance are independent. Choose the most correct (closest) answer below?

a.a chi-square test of independence requires numerical variables and you cannot do this problem.

b.Your pvalue is 0.643, and you reject your null hypothesis.

c.your pvalue is 0.322, and you fail to reject your null hypothesis.

d.your pvalue is 0.643, and you fail to reject your null hypothesis.
