An instructor collected data on the number of states that 50 students in her class had visited in the U.S. The results are shown in the 6.1.11 dotplot.

a. Use the dotplot to find and report the median value for the number of states visited by the students in this study.
b. Use the dotplot to determine the lower and upper quartile values and the inter-quartile range for the number of states visited by the students in this study.
c. Would the mean value for these data be smaller than, larger than, or the same as the median, as reported in part (a)? Explain your reasoning.
