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 differs in variability in the seventh month and the rst month after installation? Let 0] denote the variability in time to freeze-up in the rst month after installation. Use the a=0.10 level and the critical value method with the table. One month: 235.1 225.6 244.4 245.3 207.4 233.1 Seven months: 84.3 53.2 127.3 149.4 156.4 103.3 Send data to Excel H1: 01;an2 This is a two-tailed V test. The critical value f0.05 is [:l
