Prof. Murphy, always interested in improving her teaching effectiveness, has decided to undertake a careful analysis of her student evaluations from the past several years. The last question on the student evaluation form, Question17, is "Would you recommend this professor to another student?" A matter of special concern to Prof. Murphy is how she is viewed by students of different majors. Each of Prof. Murphy's students can be placed into a category according to the student's major school. (Students who have majors from more than one school are not included.) So, there are two variables under consideration: student's major school ("School of Social Sciences", "School of Engineering", or "School of Physical Sciences") and answer to Question17 ("No", "Maybe", or "Yes").The contingency table below contains a summary of the responses to Question 17 for a random sample of500 of Prof. Murphy's students. In each cell of the table is written three numbers: the first number is the observed cell frequency (fO); the second number is the expected cell frequency (fE) under the assumption that the variables student's major school and answer to Question 17 are unrelated; and the third number is the following value.Could not fit part 2 in the picture but the questions are asking for: type of test statisticvalue of test statistic p valueand can professor murphy conclude that the variable students major school and answer to question 17 are related? use the 0.05 level of significance. yes or no
