Based on the boxplot above, identify the 5 number summary

Solution
To identify the five-number summary based on a boxplot, we need to extract the following values:
- Minimum: The lowest value, represented by the left-most edge of the boxplot (whisker).
- Q1 (First Quartile): The value that represents the 25th percentile of the data, typically where the left side of the box (the box itself) begins.
- Median (Q2 or Second Quartile): The value that splits the data in half, represented by the line in the center of the box.
- Q3 (Third Quartile): The value that represents the 75th percentile of the data, typically where the right side of the box ends.
- Maximum: The highest value, represented by the right-most edge of the boxplot (whisker).
From the description, it's difficult to interpret specific numerical values without seeing the graph. However, based on the lines and box outlined in the script, you should be able to visually identify these points on the boxplot.

Tip: When analyzing a boxplot, remember that the box represents the interquartile range (IQR), and any data points outside of 1.5 times the IQR from the quartiles are potential outliers!
