The moral of the story is: Higher confidence levels tend to produce wider confidence intervals. When looking at Figure 8.29 it is important to keep in mind that we kept the sample size fixed at \(n\) = 50. Thus, all \(10 \cdot 3 = 30\) random samples from the bowl had the same sample size. What happens if instead we took samples of different sizes? Recall that we did this in Subsection 7.2.4 using virtual shovels with 25, 50, and 100 slots.
