Question

Real-time scheduling with 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 Can you conclude that there is a statistically significant difference between the two scheduling methods?

Explanation / Answer

we will apply match pair test on above data as task are same for both Human and Auto operations

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