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 freezeup 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 {:1 denote the variability in time to freezeup in the first month after installation. Use the u = 0.10 level and the critical value method with the table. Onemonth: 225.6 244.4 245.3 201.4 233.1 215.9 Seven months: 34.3 53.2 246.2 149.4 156.4 103.3 .;_ Send data to Excel '7' Part: 1} I 5 State the nu! and alternate hypoiesis- Hozm H1:D This is a (Choose one) Y tESt
