A randomized experiment was designed and conducted to test the efficiency of five insulating materials. Samples of each material were tested with a high voltage level to accelerate failure time. The failure time (in minutes) is shown in the table. Use = 0.04.

A randomized experiment was designed and

c. Determine a confidence interval for the difference in the average life of the insulating material when materials 3 and 5 are used. Use = 0.04.
