Answer:
A. The data is symmetric and shows that he typically sent about 6 to 8 text messages per day
Step-by-step explanation:
Taking a look at the dot plot given in the attachment below, we can observe that most of the data set are concentrated in the middle of the dot plot than both ends of the dot plot. With this, we can infer that the distribution of the data is symmetric.
The dot plot also tells us that, 6 and 8 text messages have more frequency than any other data set on the dot plot. This also suggests that Reza usually sends 6 to 8 messages in a day.
Therefore, the statement that is true about the dot plot is:
"A. The data is symmetric and shows that he typically sent about 6 to 8 text messages per day"
