Question

a desktop has a boot-up speed that drives you mad. A test is devised to measure the time, X, required to boot the machine into the ready-to-run state. Each time the machine is powered up, the boot time is noted. After 200 power cycles, the test is complete. It is found that X produces a value of 9.6 minutes when evaluated, with S2 taking the value of 0.72. The claim μX < 10 will form the basis of a hypothesis test at the 0.050 level.

Part 3a: State the null and research hypotheses.

Part 3b: Describe the exact location of the critical region for
this test. [That is, the presence of μ? in this region will cause
the null hypothesis to be rejected.]

Part 3c: What is the statistical conclusion to be reached?
