Scenario F.16 Three universities in your state have decided to administer the same comprehensive examination to the recipients of MBA degrees from the three institutions. From each institution , a random sample of MBA recipients has been selected and given the test. The data in the Excel file: Final exam data.xlsx (on the MBA tab) shows the scores of the students from each university. We would like to test and determine if there is any significant difference in the average scores of the students form the 3 universities.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

A study of the career plans of young women and men sent questionnaires to 722 students of class at one University. One question asked which major within the business program the student had chosen. With data we test a statement: Does the data suggest that there is a relationship between the gender of students and their choice of major? We calculated the p-value and it is 0,0127 and the level of significance is 0,05. The conclusion to the test is: a. there is sufficient evidence to conclude that the choice of major and the gender of the student are not independent of each other. b. there is insufficient evidence to conclude that more females prefer administration than males c. there is insufficient evidence to conclude that the choice of major and the gender of the student are not independent of each other. d. there is sufficient evidence to conclude that students find economics very hard.
