A computer system administrator noticed that computers running a particular operating system seem to freeze up more often as the installation of the operating system ages. She measures the time (in minutes) before freeze-up for 6 computers one month after installation and for 6 computers seven months after installation. The results are shown. Can you conclude that the time to freeze-up is less variable in the seventh month than the first month after installation? Let o1 denote the variability in time to freeze-up in the first month after installation. Use the a=0.01 level and the critical value method with the table. One month Seven months 215.9 127.3 235.1 201.3 225.6 174.2 244.4 246.2 245.3 149.4 207.4 156.4
