In order to investigate whether samples of 20 sub-regions are more likely to produce better estimates than samples of 10 sub-regions, you will need to consider repeated sampling results for samples of size 20.
Here is the stem and leaf plot for 100 estimates of sample size 10:
Here is the stem and leaf plot for 100 estimates of sample size 20:
Compare the two distributions above. In particular, look at how many estimates for each fall in the interval 450 to < 550 (i.e., the 4H and 5L stems). What does this suggest about the effect of sample size on the accuracy of estimation?
Which distribution has more estimates "closer" to the actual answer of 500? Close Tip
Now let's revisit our table of intervals.
Use the 100 estimates from samples of size 20 to determine the proportion of estimates in each of the intervals.
