The median number of part-time employees at fast-food restaurants in a particular city was known to be 18 last year. City officials think the use of part-time employees may be increasing. A sample of nine fast-food restaurants showed that seven restaurants were employing more than 18 part-time employees, one restaurant was employing exactly 18 part-time employees, and one restaurant was employing fewer than 18 part-time employees. Can it be concluded that the median number of part-time employees has increased? Test using alpha=.05 .
An MBA student wants to answer the question "How does an MBA major affect the number of job offers received?" He randomly sampled four recent graduates in each of the following three MBA majors [Finance (x1), Marketing(x2) and Management(x3)] and asked each of them to report the number of job offers. He obtains the following results. Sum of square between majors (SSB) = 62.17 Mean of square within majors (MSW) = 2.28 Mean number of job offers received from each MBA major are as follows: Finance major (x1) = 2.25 Marketing major (x2) = 3.25 Management major (x3) = 7.5
