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 freezeup differs in variability in the seventh month and the first month after installation? Let 01 denote the variability in time to freezeup in the first month after installation. Use the (X :0.05 level and the critical value method with the table. Onemonth: 215.9 235.1 225.6 244.4 2-5.3 207.4 Seven months: 127.3 201.3 174.2 246.2 19.4 84.3 Send data to Excel State the null and alternate hypothesis. a '6126 2 HO: H: 1 Clio: This is a twotailed v l test.
