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 less variable in the seventh month than the first month after installation? Let , 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. Part: 0/5 State the null and alternate hypothesis. H: H: One month: 245.3 Seven months: 149.4 207.4 233.1 215.9 235.1 225.6 156.4 103.3 84.3 53.2 127.3 Send data to Excel 0 Espanol 8 olo
