Question

Use the histogram shown.

The histogram shows the scores on a recent science test.
Select all of the statements about the data that are NOT true

A histogram titled scores on science test shows the number of students who received certain test scores. The data is as follows. Score of 61 to 70: 4 students. Score of 71 to 80: 12 students. Score of 81 to 90: 16 students. Score 91 to 100: 8 students.

Only 2 students scored less than 71 on the test.


More than half of the students scored 81 or better on the test.


More students scored between 91 and 100 on the test than scored between 71 and 80.


There were 12 students who scored 80 on the test.


The same number of students scored between 81 and 90 on the test as scored between 61 and 80.

Answer 1

If a histogram titled scores on science test shows the number of students who received certain test scores. The statements that are NOT true are 1 and 4.

What are the true statement?

1. This statement is NOT true. According to the data, there are 4 students who scored between 61 and 70, which is more than 2.

2. This statement is TRUE. There are 16 students who scored between 81 and 90, and 8 students who scored between 91 and 100. In total, 24 students scored 81 or better, which is more than half of the total number of students.

3. This statement is TRUE. There are 8 students who scored between 91 and 100, which is more than the 12 students who scored between 71 and 80.

4. This statement is NOT true. The histogram data does not provide information about exactly how many students scored 80. It only indicates the ranges in which students scored.

5. This statement is NOT true. There are 16 students who scored between 81 and 90, which is not the same as the number of students who scored between 61 and 80, which is 4 + 12 = 16.

Therefore, the statements that are NOT true are 1 and 4.
