Please help :(

Step-by-step explanation:

Remember that a box plot shows the quartiles of the data set, the minium value and the maximum value.

In this case, the lowest score was 40, that means A is correct.

The interquartile range is the difference between the first and the third quartile, which is 90-70= 20. So, B is correct.

The line inside the box represents the second quartile, which is also the median of the data set, in this case, the median is 75. Now, the median is calculated with the mean between the 5th and 6th score. That means E is correct.

Therefore, the right choices are A, B and E.
