Answer:
a) False
b) False
c) False
d) True
Step-by-step explanation:
Since it is not a multiple choice question, I have answered it as a true/false question.
First, let's identify where Jimmy's score (an 85) lies in the box-and-whisker plot. It is on the upper quartile, which is also a 75% or ¾ mark compared to the scores his classmates obtained.
To the right, are those that score better than Jimmy (the scores increase to the right). Thus, to find the fraction of students that scored higher than him, we take 1 whole minus ¾, which would give us ¼.
Fraction of students that scored lower than Jimmy= ¾
(Since when we count the position of Jimmy's score, we count it with respect to the lowest score in the class.)
