Well it's not that complicated

All that you need to do is add 3 hours to each of the times, then do the thing for mean median and mode

Or you could just find all the things according to that table, then add 3 onto the mean, median, and mode

Answer 15

Think in "blocks". A value (like 13) receives one block per number of times it appears in the data.

So,
23, 13, 13, 14, 16, 20, 18 are the values.

The median is the `value` such that: on the left side and the right side of that value, there's half of the number of values. Which value separates the blocks like this?
