The yield (larger-the-better) on an old chemical process for five days is 61, 63, 58, 57, and 60.
S/N ratio = 
= 59.8/2.1354
= 28
The new process had yields of 54, 56, 52, 56, 53, 51, 54, 53, and 52.
S/N ratio =
= 53.4444/1.6405
= 32.58
Yes, the new process have a better S/N ratio.

West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TOM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the time above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to...
