Explanation:

Step1: Recall measure definitions

The mode is the value that appears most frequently in a data - set. In part (a), we want the age shared by the most residents, which is the definition of the mode.

Step2: Analyze part (b) data

The data set for miles driven has an outlier (763). The mean is affected by outliers, while the median is not. So, the median is a better measure to summarize the data.

Step3: Analyze part (c) data

There are no extreme outliers and no repeated values that stand out. The mean takes into account all values in the data - set and can be used to summarize the data.

Answer:

(a) Mode
(b) Median
(c) Mean
