Question

2. It is thought that a new process for producing a certain chemical may be cheaper than the currently used process. Each process was run 6 times, and the cost of producing 100L of the chemical was determined each time. The results, in dollars, were as follows:

New Process: 51, 52, 55, 53, 54, 53
Old Process: 50, 54, 59, 56, 50, 58

Can we conclude that the mean cost of the new method is less than that of the old method? Use a 0.01 level of significance.
