# The hand spans, to the nearest cm, of some students in a class are shown below: 19, 22, 21, 15, 18, 22, 17, 19, 16, 21, 19, 18, 22, 20, 21, 22, 19, 15, 17, 21 Henry created the following incorrect dot plot to represent the data: Dot plot showing 2 dots over 15, 1 dot over 16, 2 dots over 17, 2 dots over 18, 4 dot over 19, 1 dot over 20, 5 dots over 21, and 4 dots over 22 What should Henry do to make the dot plot correct?

###### Question:

## Answers

Your Answer is D, delete 1 dot on 21.

Answer:He should remove one dot over 21 so that the actual data plot and his data plot matches.Step-by-step explanation:We are given a set of data points as:19, 22, 21, 15, 18, 22, 17, 19, 16, 21, 19, 18, 22, 20, 21, 22, 19, 15, 17, 21 on making the frequency table of these data points. Hand span(cm) Frequency 15 2 16 1 17 2 18 2 19 4 20 1 21 4 22 4Hence, when we will make the dot plot of it then:There must be: 2 dot over 151 dot over 162 dot over 172 dot over 184 dot over 191 dot over 204 dot over 21and 4 dot over 22But according to Henry it was given:2 dots over 151 dot over 162 dots over 172 dots over 184 dot over 191 dot over 205 dots over 21and 4 dots over 22Hence, Henry should remove one dot over 21 in order to get the correct dot plot.
