Question

The dot plot below shows the number of passengers in some cars:

A dot plot with integers 1 to 5 is shown. It is labeled Passengers, and titled Passengers in Cars. There is 1 dot above 1, 1 dot above 2, 2 dots above 3, 5 dots above 4, and 4 dots above 5.

Which of the following statements best describes the shape of the data?

It is symmetric and has a peak at 5.
It is symmetric and has a peak at 4.
It is not symmetric and has a peak at 5.
It is not symmetric and has a peak at 4.

Answer 1

it is not symmetric and has a peak at five

Explanation:

Answer 2

The statement which best describe the shape of the data is:

• It is not symmetric and has a peak at 4.

Explanation:

A dot plot is said to be symmetric if the plot to the left and right hand side of the mean is roughly the same.

Here by looking at the dot plot we see that the data is not symmetric as it is not equally divided to the left and right of the mean.s

Also, the peak is at the point at which the frequency i.e. the dots are the highest.

Hence, from the dot plot we observe that the peak is at: 4

( Since the frequency at 4 is highest i.e. 5)
