The university data center has two main computers. The center wants to examine whether computer 1 is receiving tasks which require
comparable processing time to those of computer 2. A random sample of 10 processing times from computer 1 showed a mean of 37 seconds
with a standard deviation of 20 seconds, while a random sample of 12 processing times from computer 2 (chosen independently of those for
computer 1) showed a mean of 59 seconds with a standard deviation of 18 seconds. Assume that the populations of processing times are
normally distributed for each of the two computers, and that the variances are equal. Can we conclude, at the 0.05 level of significance, that
the mean processing time of computer 1, µ, differs from the mean processing time of computer 2, µ,?
Perform a two-tailed test. Then fill in the table below.
Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult
a list of formulas.)
