The number of text messages that reza sent each day so far in this billing cycle is shown on the dot plot.

which statement must be true according to the dot plot?

a) the data is symmetric and shows that he typically sent about 6 to 8 text messages per day.

b) the data is symmetric and shows that he sent 11 or 12 texts with the same frequency that he sent 1 or 2 texts.

c) the data is skewed and shows that he typically sent about 6 to 8 text messages per day.

d) the data is skewed and shows that he sent 11 or 12 texts with the same frequency that he sent 1 or 2 texts.

A) The data is symmetric and shows that he typically sent about 6 to 8 text messages per day.

Step-by-step explanation:

We can represent the given dot plot in form of table as:

Text messages per day                 Frequency

         1                                                  0

         2                                                 2

         3                                                 1

         4                                                 0    

         5                                                 0

         6                                                 3  

         7                                                  2      

         8                                                  3  

         9                                                  0

         10                                                 0

         11                                                  1  

         12                                                 2

         13                                                 0    

Clearly from the dot plot we could observe that the data is symmetric because there are equal number of messages sent to the left and right of 7.

i.e. the left of the dot plot is a mirror image to the right of the dot plot.

Also, the data is not skewed it is symmetric.

Also, the maximum number of text were sent about 6 to 8.

As the frequency is higher in that interval.

Hence, option: A is the correct answer.
