Prof. Cook, always interested in improving her teaching effectiveness, has decided to undertake a analysis of her student evaluations from the past several years. The last question on the student form, Question 17, is "Would you recommend this professor to another student?" A matter of spec to Prof. Cook is how she is viewed by students of different majors. Each of Prof. Cook's students c placed into a category according to the student's major school. (Students who have majors from one school are not included.) So, there are two variables under consideration: student's major scr ("School of Social Sciences", "School of Engineering", or "School of Physical Sciences") and answe Question 17 ("No", "Maybe", or "Yes"). The contingency table below contains a summary of the responses to Question 17 for a random sa 500 of Prof. Cook's students. In each cell of the table is written three numbers: the first number is observed cell frequency (fo); the second number is the expected cell frequency…

H0: The response of the subject and the gender of the subject are independent. H1: The response of the subject and the gender of the subject are dependent. B. H0: The proportions of agree/disagree responses are different for the subjects interviewed by men and the subjects interviewed by women. H1: The proportions are the same. C. H0: The proportions of agree/disagree responses are the same for the subjects interviewed by men and the subjects interviewed by women. H1: The proportions are different. Compute the test statistic. Find the critical value(s). What is the conclusion based on the hypothesis test? Fail to reject/ Reject H0. There is/is not sufficient evidence to warrant rejection of the claim that the…
Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.
