Question

The line plot below shows how students fared in last week's mathematics test.

Math test scores:

(i) How many students scored 95 or more in the test?
(ii) How many students scored 85 or less in the test?

Answer 1

(i) Number of students who scored 95 or more than 95

= number of students who scored 95 + number of students who scored 100

= 7 + 5 = 12

Only 12 students scored 95 or more in the test.

(ii) Number of students who scored 85 or less

= number of students who scored 85 + number of students who scored 80 + number of students who scored 75 + number of students who scored 70

= 3 + 2 + 1 + 1 = 7

Only 7 students scored 85 or less in the test.
