Answer:

Lower Quartile (Q1) = 19; Upper Quartile (Q3) = 38.

Step-by-step explanation:

To find the quartiles, we begin by finding the median (Q2). The median is the middle value; this is 25.

The median splits the data into half. The median of the lower half is 19; this is the lower quartile. The median of the upper half is 38; this is the upper quartile.
