The standard deviation (or, as it is usually called, the standard error) of the sampling distribution for the sample mean, , is equal to the standard deviation of the population from which the sample was selected, divided by the square root of the sample size. That is,

a. As the sample size is increased, what happens to the standard error of ? Why is this property considered important?

b. Suppose a sample statistic has a standard error that is not a function of the sample size. In other words, the standard error remains constant as n changes. What would this imply about the statistic as an estimator of a population parameter?

c. Suppose another unbiased estimator (call it A) of the population mean is a sample statistic with a standard error equal to

Which of the sample statistics,  or A, is preferable as an estimator of the population mean? Why?

d. Suppose that the population standard deviation σ is equal to 10 and that the sample size is 64. Calculate the standard errors of  and A. Assuming that the sampling distribution of A is approximately normal, interpret the standard errors. Why is the assumption of (approximate) normality unnecessary for the sampling distribution of ?

Even in these tough economic times, some companies continue to spend lavishly on unusual employee perks such as massages and  sauna visits, hold on to generous compensation and benefits, and don’t lay off workers as a matter of principle. At the same time, they remain profitable. Chances are that you haven’t heard of the newest top three among Fortune’s 100 Best Companies to Work For—tech giant SAS, investment advisor Edward Jones, and New York–based Wegmans  Food Markets. The perennial favorite, Google, slipped to fourth place. Fourteenth-ranked outdoor powerhouse REI attracts active types who may bring their dogs to work, go on a midday bike ride, and test the products they sell. Sound nice? Just as companies have their distinctive corporate cultures, they also differ in why they are perceived as ideal employers.
