Applet Exercise Refer to Exercise 9.13. Scroll down to the portion of the applet labeled “Mean of Normal Data.” Successive observed values of a standard normal random variable can be generated and used to compute the value of the sample mean \(\bar{Y}_{n}\). These successive values are then plotted versus the respective sample size to obtain one “sample path.”
a Do you expect the values of \(\bar{Y}\)n to cluster around any particular value? What value?
b If the results of 50 sample paths are plotted, how do you expect the variability of the estimates to change as a function of sample size?
c Click the button “New Sequence” several times. Did you observe what you expected based
on your answers to parts (a) and (b)?
