Refer to Why Divide by n - 1 applet. The second applet on the page randomly selects sample of n = 10 from the same population in which the standard deviation is σ = 29.2.

a. Repeat the instructions in part c and d of Exercise 2.89.

b. Based on your simulation, when the sample size is larger, does it make as much difference whether you divide by n or n
1 when computing the sample standard deviation?

In Exercise

c. You can look at how the two estimators in part a behave “in the long run” by clicking or a number of times, until the average of all the standard deviations begins to stabilize. Which of the two methods gives a standard deviation closer to σ = 29.2?

d. In the long run, how far off is the standard deviation when dividing by n?
