Question

Real-time scheduling until robots. Researchers at Purdue University compared human real-time scheduling in a processing environment to an automated approach that uses robots and sensing devices. The experiment consisted of 8 simulated scheduling problems. Each task was performed by a human scheduler and again by the automated system. Performance was measured by the throughput rate, which is the number of jobs completed during the experiment. The results for this experiment are in the spreadsheet "THRUPUT" _________ Can you conclude that there is a statistically significant difference between the two scheduling methods? TASK HUMAN AUTO 1 185.4 180.4 2 146.3 248.5 3 174.4 185.5 4 184.9 216.4 5 240 269.3 6 253.8 249.6 7 238.8 282 8 263.5 315.9

Explanation / Answer

applying matched pair t test on above:

as p value is less then 0.05 level we can conclude that there is significant differnce b/w two scheduling methods
