There is one 1....so the one dot over the 1 is correct
There are four 2's....so the 4 dots over the 2 is correct

Answer:

Number 4 plot incorrectly represent on dot plot.

C is correct

Step-by-step explanation:

The following data show the number of questions different students of a class could answer in a quiz competition:

2, 4, 2, 5, 1, 4, 5, 7, 3, 5, 6, 2, 2, 5, 5, 5, 4, 6

We are given the dot plot of the data set.

 Data            :    1     2     3    4     5     6     7    

Frequency   :    1     4     1     3     6     2     1

We need to choose which data number plot incorrectly.

For 2: Number of dot should be 4, In graph also 4, 4=4 (True)

For 3: Number of dot should be 1, In graph also 1, 1=1 (True)

For 4: Number of dot should be 3, In graph also 2, 3≠2  (False)

For 5: Number of dot should be 6, In graph also 6, 6=6  (True)

Hence, number 4 plot incorrectly
