A father notes that when his teenage daughter uses the phone she takes...
Makes 20-minute calls more frequently than calls of any other duration, it can be inferred that the distribution of call durations is not evenly distributed.

To further analyze the distribution, let's assume that the daughter makes calls of length x minutes more frequently than calls of any other duration.

Since the father notes that the daughter takes no less than 6 minutes for a call, we can assume that x > 6.

The father also notes that the daughter sometimes takes as much as an hour for a call, which is equal to 60 minutes. This means that x < 60.="" />

Based on the given information, we can conclude that the daughter's calls duration distribution is skewed towards the 20-minute mark, with a range between 6 and 60 minutes.
