Answer 1

Given:

data set of people who reported on how many soft drinks they drank in the last month.

8, 28, 30, 31, 32, 34, 35, 36, 39

The data type given is an interval data type, which would imply that the mean is the best choice here however, there is a clear outlier in the data type (which is 8), and the measure that is less prone to outliers is median. Hence, the median is the best measure to summarize the data.
