Determine the appropriate hypothesis test(s) to be used in the four research projects described below. In selecting the appropriate test(s), describe the test selection procedure, include each of the following factors: Null hypothesis (Ho) Alternative hypothesis /hypothesis (HA) Measurement scale/data type: nominal, ordinal, interval or ratio Sample description Number of samples: 1,2 or 3 or more If samples are independent or related Hypothesis test(s) to be used Describe any other issues/assumptions that should be considered. In some cases, more than one test may apply. (25 points each) NOTE: No Calculations are needed) Five thousand randomly selected MBA graduates were surveyed to determine their future plans. The survey response rate was 10%. The graduates' future plans were grouped into four categories for each of thee majors, as shown in the following table: FUTURE PLANSMarketing (204)Finance (172)Operations (124) Continue their education26%21%24% New position – existing company39%38%41% New position – different company23%28%26% Not sure 12%13%9% The Business School Dean wants to determine if the future plans are significantly different for the three majors at a level of confidence of at least 90%. What test(s) would you recommend? A company hired 30 salespeople and gave them an initial sales skills examination: test scores ranged from 68 to 95, with a mean of 77.4. All salespeople then attended a two-week training program and were re-tested, test scores ranged from 65 to 98, with a mean score of 83.2.
