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 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: 244.4 245.3 207.4 233.1 215.9 235.1 Seven months: 84.3 53.2 127.3 201.3 156.4 103.3 Send data to Excel Part: 0 / 5 State the null and alternate hypothesis. Ho This is a (Choose one) v test
