Need help finding the critical value and F=

Frozen computer; A computer system administrator noticed that computers running a particular operating system seem to freeze up more often as the Espanol 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 more variable in the seventh month than the first month after installation? Let o, 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: 225.6 244.4 245.3 207.4 233.1 215.9 Explanation Seven months: 84.3 53.2 246.2 149.4 156.4 103.3 Send data to Excel State the null and alternate hypothesis.
