A systems analyst tests a new algorithm designed to work faster than the currently-used algorithm. Each algorithm is applied to a group of 50 sample problems. The new algorithm completes the sample problems with a mean time of 10.22 hours. The current algorithm completes the sample problems with a mean time of 12.91 hours. The standard deviation is found to be 4.905 hours for the new algorithm, and 5.149 hours for the current algorithm.

Question
A systems analyst tests a new algorithm designed to work faster than the currently-used algorithm. Each algorithm is applied to a group of 50 sample problems. The
new algorithm completes the sample problems with a mean time of 10.22 hours. The current algorithm completes the sample problems with a mean time of 12.91
hours. The standard deviation is found to be 4.905 hours for the new algorithm, and 5.149 hours for the current algorithm. 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. Let u, be the true mean completion time for the new
algorithm and uz be the true mean completion time for the current algorithm.
Step 1 of 4: State the null and alternative hypotheses for the test.
