box plot with minimum value 8.3, lower quartile 8.5, median 8.6, upper quartile 8.7, and maximum value 8.9
box plot with minimum value 8.2, lower quartile 8.3, median 8.4, upper quartile 8.6, and maximum value 8.9

Answer 1

B

Step-by-step explanation: took the test

Answer 2

The min value is the smallest value of data in the list, which is 8.2. The max is 8.9. Ranking all the numbers from smallest to largest, we found that 8.4 is in the 5th place, right in the middle, so it's the median. the upper quartile (bigger than 75% of data) number is 8.5, while the lower quartile (bigger than 25% of data) is 8.3.
