A professor wonders whether an unusual number of freshmen students are enrolled in his NINJ402 Advanced Ninja Warrior class, which is usually populated primarily by upperclass students (so, usually a 5/10/25/60% split, percentage- wise). In his present class, there are 8 freshmen, 3 sophomores, 9 juniors, and 15 seniors. Conduct the appropriate chi- square test. a) State the hypotheses (1): Ho H1: b) Calculate the test statistic. (2) What type of test is this? a) Goodness-of-Fit, or b) Independence? What answer did you get for your chi-square statistic? d) State your conclusions (statistically and in terms of the research question), assuming a critical value of 9.48 for a=.05. (2) x²( Sentence: ) = , p .05
