Ten sixth-grade students recorded the amounts of time each took to travel to school. The dot plot shows their travel times.
The mean travel time for these students is approximately 9 minutes. The MAD is approximately 4.2 minutes.
A different group of ten sixth-grade students also recorded their travel times to school. Their mean travel time was also 9 minutes, but the MAD was about 7 minutes. What could the dot plot of this second data set be? Describe or draw how it might look.

In an archery competition, scores for each round are calculated by averaging the distance of 3 arrows from the center of the target.
An archer has a mean distance of 1.6 inches and a MAD distance of 1.3 inches in the first round. In the second round, the archer's arrows are farther from the center but are more consistent. What values for the mean and MAD would fit this description for the second round? Explain your reasoning.
