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?
