Hope this helps!
the only statement that is true is the one in option D.
"Bar graphs are used to represent data that is discrete".
<h3>Which of the statements are true regarding dot plots, bar graphs, and histograms?</h3>
Dot plots, bar graphs, and histograms are used to repersent graphically data sets.
Thus, what these graphs do represent are populations in a data set with a given property.
Remember that data is usually discrete, so we usually use dot plots and bar graphs to represent discrete data.
Histograms show distributions of numerical data (it can be used for continuous or discrete data).
With all that in mind, we conclude that the only statement that is true is the one in option D.
"Bar graphs are used to represent data that is discrete".

Answer:
The 99% confidence interval is 
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
Given that confidence is 99% then the level of significance is mathematically represented as
Next we obtain the critical values of 
from the normal distribution table
The value is
Generally the margin for error is mathematically represented as
=> 
=> 
The 99% confidence interval is mathematically represented as
=> 
=>
