A human-resource department manager is interested in which work schedule makes the employees the most satisfied. The manager randomly divides the employees into two groups and have onethem scheduled to work between9am-5pmand the other between 6am-2pm. After the employees work withtheir schedule for a month, the manager sends out a “Job Satisfaction Survey” to everyone. The survey includes statementssuch as “I am happy with my job.” “I am glad I am working here.” etc.and the employees rank how much they agree with the statement on a scale of 1 to 10where higher numbers indicate more agreement.The results are below:9am-5pmschedule: Xi: 6,6,5,4,7,9,2,3,9,10,9,7,6,106am-2pmschedule: Xi:1,2,1,4,2,5,10,10,10,3,2,1,4,3 a.Identify the predictor and predicted variables. b.Determine if the studyisexperimental or non-experimental, explain why. c.Describe the levels of measurement for the variables, explain why. d.For both groups, report on the central tendencyby calculating the mean, median, mode. e.For both groups, report on the variabilityby calculating therange, variance, and standard deviation. f.For both groups, report on the kurtosis and skewness of the data. g.What do you thinkis the outcome of the study? Comment, feel free to draw the distributions.
