Answer:
A
Explanation:
When reading the box and whisker plot, the line drawn at 9 is the median, meaning that half the cats are between 7 and 9 pounds while another half of the cats are from 9 to 15 pounds. The two ends of the boxes are the medians of their respective halves, creating what are known as 4 quartiles. That means that a quarter of the cats are inbetween ages 7-8, a quarter are between 8 and 9, a quarter is between 9 and 11 and another quarter is between 11 and 15.
Answer B is incorrect because only 25% of the cats are below 8 pounds.
Answer C and D are incorrect because only 25% of the cats are above 11 pounds.
Thus, by process of elimination, answer A is the correct answer
