- Notice that the width (difference between upper and lower bounds) of the confidence interval shrinks as n grows. This matches our intuition that more data will result in better estimates. | - Notice that the width (difference between upper and lower bounds) of the confidence interval shrinks as n grows.

- Produce a table summarizing your results. Include the value of n, the number of successful trials at each distance, your estimates of the probabilities p<sub>20</sub>, p<sub>40</sub>, and p<sub>60</sub>, and the 95% confidence intervals for each estimate. | - Produce a table summarizing your results.

- Answer these questions: is one system better for all distances? Or, does the answer to this question depend upon the distance, e.g., is one system better at 20 feet and the other system better at 40 feet? | - Answer these questions: is one system better for all distances?
