A population has a mean of 79 and a standard deviation of 27. Sample means are computed for several thousand random samples of size ? = 81, and a relative frequency histogram is constructed for the sample means.
1. What kind of shape would you expect the histogram of the sample size to have?
2. What value would you estimate for the mean of the histogram of sample means?
3. What value would you estimate for the standard deviation of the histogram of sample means?
(1) The histogram can be expected to have a bell-shape (similar to that of the ...
