Answer:
A
Step-by-step explanation:
First find the median of the data set.
The median is the middle value of the data set arranged in ascending order
10, 11, 12, 15, 17, 19, 22, 24, 29, 33, 38
The median = 19
The first quartile ( lower) is the middle value of the data to the left of the median.
10, 11, 12, 15, 17
The first quartile is 12 → A
