8.5
Select 10 additional random samples of size 5 from the population of 20 students given in Example 8.1, and compute the mean amount spent on books for each of the 10 samples. Are the x values consistent with the results of the sampling experiment summarized in Figure 8.1?
8.6 Suppose that the sampling experiment described in Example 8.1 had used samples of size 10 rather than size
2.
If 50 samples of size 10 were selected, the x value for each sample computed, and a density histogram con- structed, how do you think this histogram would differ from the density histogram constructed for samples of size 5 (Figure 8.1)? In what way would it be similar?
