              Question:
              Multiple choices based on the chi square test.

         ClassOf1 provides expert guidance to College, Graduate, and High school students on homework and assignment problems in
                       Math, Sciences, Finance, Marketing, Statistics, Economics, Engineering, and many other subjects.

              Recently, students in a marketing research class were interested in the driving behavior of
              students. Specifically, the marketing students were interested if exceeding the speed limit was
              related to gender. They collected the following responses from 100 randomly selected
              students:

                          Speeds          Does not speed

              1. The appropriate test to analyze the relationship between gender and education is:

                    A. regression analysis

                    B. Analysis of variance

                    C. Contingency table analysis

                    D. Goodness-of-fit

                    Ans: C

              EXPLANATION:
              There are basically two types of random variables and they yield two types of data: numerical
              and categorical. A chi square ( ) statistic is used to investigate whether distributions of
              categorical variables differ from one another.

              Contingency table: A table that classifies each element of a sample according to two distinct
              characteristic. In our problem, we need to analysis to two distinct characteristic that is
