What is the third quartile (rounded to the nearest tenth if needed) of the following data set: 15, 16, 17, 23, 11, 19, 20, 15, 18, 22, 15(1 point) Responses 20 20 17 17 15 15 17.4

1 answer

The third quartile of the data set can be found by first arranging the data in numerical order:

11, 15, 15, 15, 16, 17, 18, 19, 20, 22, 23

The median of the dataset lies between 16 and 17, so the third quartile (Q3) is 17.
