A systems analyst tests a new algorithm designed to work faster than the currently-used algorithm. Each algorithm is applied to a group of 56 sample problems. The new algorithm completes the sample problems with a mean time of 10.32 hours. The current algorithm completes the sample problems with a mean time of 10.51 hours. Assume the population standard deviation for the new algorithm is 5.268 hours, while the current algorithm has a population standard deviation of 5.279 hours.
Required:
Conduct a hypothesis test at the 0.05 level of significance of the claim that the new algorithm has a lower mean completion time than the current algorithm.
