Use MINITAB to solve the following:

Free Memory
1493
1319
1253
1651
1812
1682
1737
1193
1893
1532

1842

Data were collected on the amount of free memory during peak usage times of the AIX system on a university campus. The unit used was real memory page (4096 bytes). Suppose that the free memory is normally distributed. Using a significance level of 0.02, is there evidence that the standard deviation in the population of free memory during peak usage time is different from 100?
