- Daniel Glaser, chairman of the College of San Antonio’sbusiness department, needs to assign professors to courses nextsemester. As a criterion for judging who should teach each course,Professor Glaser reviews the past 2 years’ teaching evaluations (which were filled out by students). Since each of the four profes-sors taught each of the four courses at one time or another during the 2-year period, Glaser is able to record a course rating for eachinstructor. These ratings are shown in the following table.a) Find the assignment of professors to courses to maximize theoverall teaching rating.b) Assign the professors to the courses with the exception thatProfessor Fisher cannot teach statistics.

That show recently had a share of 19, which means, that among the TV sets in use, 19% were tuned to CSI: Shoboygan. An advertiser wants to verify that 19% share value by conducting its own survey, and a pilot survey begins with 12 households have TV sets in use at the time of a CSI: Shoboygan broadcast.The director of the MBA program at Salterdine University wants to develop a procedure to determine which applicants to admit to the MBA program. The director believes that an applicant’s undergraduate grade point average (GPA) and score on the GMAT exam are helpful in predicting which applicants will be good students. To assist in this endeavor, the director asked a committee of faculty members to classify 70 of the recent students in the MBA program into two groups: (1) good students and (2) weak students. The file MBAStudents.xlsm summarizes these ratings, along with the GPA and GMAT scores for the 70 students. What are the coordinates of the centroids for the good students and the weak students? Use XLMiner’s standard data partition command to partition the data into a training set (with 60% of the observations) and validation set (with 40% of the observations) using the default seed of 12345. Use discriminant analysis to create a classifier for this data. How accurate is this…

In order to decide whether these extra sessions actuallyhelp students, he keeps track of who attends them and compares their jury scores to those of students who did not schedule extra sessions. In this study, a difference was found between the scores of students who scheduled the extra sessions and those of students who didn't attend(higher average for students with extra sessions) A) Yes, becuase the study relied on a common final exam fro everyone B)No, because the students chose whether they attended the review session or not C) Yes becuase the study included both students who attned the review session and those who did not D)Yes, becuase the number of subjects in the study was large E)No, becuase the students in the study were not blindedAccording to the Department of Motor Vehicles (DMV), the entity in charge ofprovidingdrivinglicensesintheUnitedStates,itisillegaltodrivewithabloodalcoholcontentof0.08%ormoreif you are 21 or older.
