Frozen computer: 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 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 = 0.10 level and the critical value method with the table. One month: 215.9 235.1 225.6 244.4 245.3 207.4 Seven months: 127.3 201.3 174.2 246.2 149.4 156.4 Send data to Excel State the null and alternate hypothesis.
