Answer: D - The median for the set above is $5.06.

The median is the middle number when the numbers are in ascending order ($1.16, $2.94, $3.27, $4.86, $5.25, $6.15, $7.62, $9.42). Whenever there is an even number of entries in a set, putting two numbers in the middle of the ordered entries, those two numbers are averaged to find the median. In this series of eight numbers, you must take the fourth and fifth numbers: 4.86 + 5.25 = 10.11 / 2 = 5.06

The mean is $4.07. There is no mode because each number occurs only once in the set.
