1) Kira used published data that is quantitative.
- She used census information (published/secondary data) and the number of people is numerical (quantitative).

2) The mean is the same as the median.
- Mean = (5·1 + 7·2 + 9·3 + 11·4 + 13·3 + 15·2 + 17·1) / 16 = 176/16 = 11.
- The median (average of the 8th and 9th values) is also 11.
