Question

Transcribed Image Text:Two Softwares are being analyzed to determine how they affect the mean solving time of problems. Specifically, software 1 is
currently in use, but software 2 is acceptable. Since software 2 is cheaper, it should be adopted, provided that it does not change the
solving meantime. A test is run in the pilot lab and results in the data shown in the table below. Test the claim of difference between
the meantime. Use a = 0.50
