Frozen computer: A computer system administrator noticed that computers running a particular operating system seem to freeze up more often as the Espanol 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 = 0.05 level and the critical value method with the table. One month: 233.1 215.9 235.1 225.6 244.4 245.3 Seven months: 103.3 84.3 53.2 127.3 201.3 174.2 Send data to Excel State the null and alternate hypothesis. Ho: 61 = 02 0 0=0 H1: 1 7 02 01 02Espanol Ho : 01 = 02 00 0=0 H1 : 1 > 02 0#0 01 02 This is a left-tailed test. X 5 Find the critical value. Round the answer to two decimal places. The critical value fo.05 is 2.75 X 5 Compute the test statistic. Round the answer to two decimal places.\fEspanol Determine whether to reject Ho. Reject V the null hypothesis Ho. X 5 Part: 4 / 5 State a conclusion. There is enough evidence to conclude that the time to freeze-up is less variable in the seventh month than in the first month after installation. X 5
