Question: Also need if we reject or do not reject the null hypothesis And is there or is not enough evidence Frozen computer: A computer system

Also need if we reject or do not reject the null hypothesis And is there or is not enough evidence

Also need if we reject or do not reject the null hypothesis

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 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 = 0.10 level and the critical value method with the table. One month: 215.9 235.1 225.6 244.4 245.3 207.4 Seven months: 127.3 201.3 174.2 246.2 149.4 84.3 Send data to Excel State the null and alternate hypothesis. HO: I0 0-0 This is a (Choose one) V test. X Find the critical value. Round the answer to two decimal places. The critical value fo.10 is X Compute the test statistic. Round the answer to two decimal places. X
