Refer to Exercise 8.104 and the study to compare human real-time scheduling to an automated approach that utilizes computerized robots and sensing devices (IEEE Transactions, Mar. 1993). Recall that eight simulated scheduling tasks were performed by a human scheduler and by the automated system. The resulting throughput rates are shown in the table on p. 882. Compare the throughput rates of tasks scheduled by a human and the automated method with a nonparametric test. Use α = .01.    

Data from Exercise 8.104

Researchers at Purdue University compared human real-time scheduling in a processing environment to an automated approach that utilizes computerized robots and sensing devices (IEEE Transactions, Mar. 1993). The experiment consisted of eight simulated scheduling problems. Each task was performed by a human scheduler and by the automated system. Performance was measured by the throughput rate, defined as the number of good jobs produced weighted by product quality. The resulting throughput rates are shown in the accompanying table. Analyze the data using a test of hypothesis
