Several employees of Goldman Sachs have asked to take only one long break while others requested several short breaks. In addition, some workers requested to work 4-day weeks, others flex time, and still others at the random times. The human resources department at Goldman Scahs (GS) has decided to conduct the study to find out if the different schedule kinds and the number of breaks have an effect on performance. GS hired AN&T, Inc., a company specializing in employee scheduling, to look into GS employees' concerns and their suggestions regarding the number of breaks and schedule type. A sample of 16 employees was obtained. Each employee was randomly assigned to one of the combinations of work schedules and number of breaks. The performance for each worker for a week was then recorded. At the 0.05 level is there a difference in the mean output for the various number of breaks and for different schedules?
Number of Breaks
Schedule Type 1 2 3 4
Regular 105 95 87 90
Flex time 99 90 85 80
Four-Day 110 120 100 100
Conduct the hypothesis, at 0.05 level, that in the population, there is no difference in the mean performance for the different number of breaks (1, 2, 3, and 4 breaks.)
