Box-and-whisker plot ranging from 34 to 58 with ticks at increments of one half. Plot defined by points at 35, 37, 41, 49, 55

Answer 1

In a box-and-whisker plot, the data is divided into quartiles. The first quartile (Q1) is the median of the lower half of the data (the first 50%).

From the information provided, the quartiles are given as follows:
- The first quartile (Q1) is marked at 37.
- The second quartile (Q2 or median) is at 41.
- The third quartile (Q3) is at 49.

Thus, the first quartile (Q1) of the data displayed in the box-and-whisker plot is **37**.
