Question
A computer manufacturer is about to unveil a new, fasterpersonal computer. The new machine clearly is faster, but initialtests indicate there is more variation in the processing time. Theprocessing time depends on the particular program being run, theamount of input data, and the amount of output. A sample of 16computer runs, covering a range of production jobs, showed that thestandard deviation of the processing time was 22 (hundredths of asecond) for the new machine and 12 (hundredths of a second) for thecurrent machine. At the .05 significance level can we conclude thatthere is more variation in the processing time of the new machine? Please show work!
