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…

A politician asked his constituents via a Facebook poll to help him how he should vote on a bill that would establish 150m Protester Exclusion Zones around abortion clinics in New South Wales, Australia. On his Facebook page, Philip Donato stated “I believe this is a matter of conscience and the views of my electorate should supersede my own.” After the poll closed, the final Facebook poll results had 78%78% of the 1960019600 voters indicating support for the Protester Exclusion Zones. Use our quick and approximate method to determine the margin of error for the final Facebook poll results. Give your answer as a percentage precise to two decimal places.
The control department of a light bulb manufacturer randomly picks 4400 light bulbs from the production lot every week. The records show that, when there is no malfunction, the defect rate in the manufacturing process ( due to imperfections in the material used) is 1%. When 1.25% or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following.
You are the cadet Industrial Engineer who was to check on work standards. A certain assembly task has a prescribednormal time of 25 seconds, with an allowance of 10 seconds, such that it is standardized that 95% of workers shouldbe able to finish the task within 35 seconds. The following 36 randomly timed instances of workers’ assembly times(in seconds) are available for your audit.23, 18, 27, 47, 29, 24, 18, 46, 31, 36, 22, 18, 26, 32, 15, 27, 26, 21,37, 30, 15, 19, 12, 27, 18, 17, 14, 17, 36, 42, 27, 20, 15, 26, 29, 19Use a 5% level of significance for the following:a) Is the standard deviation of the sample data consistent with the standard time of 35 secs?b) Does the data show evidence that the mean time to assemble has shifted? c) What practical implications do your results in (a) and (b) mean for the established work standardof 35 seconds? (in 50 words)d) Give the highest possible median (to the nearest second) that we could accept with 95% certainty.
