8.5Â Â
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?
Â
8.6Â Â Suppose that the sampling experiment described in Example 8.1 had used samples of size 10 rather than size
2.Â
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?
