number of these simulations and take averages, we should expect that these
values would be closer, if not equal, to each other. The main purpose of this
illustration was to help in understanding the stated properties given in
Table 10-2
.
Table 10-2:
Propertiesof the Sampling Distribution
for the Sample Proportion
Also the shape of the distribution of the simulated sample proportions is
approximately bell-shaped. That is, the distribution of the sample
proportions is approximately normally distributed. A frequency histogram
for the simulation is shown in
Figure 10-4
