Question

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? the data is symmetric and shows that he typically sent about 6 to 8 text messages per day. the data is symmetric and shows that he sent 11 or 12 texts with the same frequency that he sent 1 or 2 texts. the data is skewed and shows that he typically sent about 6 to 8 text messages per day. the data is skewed and shows that he sent 11 or 12 texts with the same frequency that he sent 1 or 2 texts.

Explanation:

Step1: Analyze the symmetry of the data

Symmetric data has a mirror - like appearance around the center. Looking at the dot - plot, the data is not symmetric. There is a longer tail on one side, so it is skewed.

Step2: Analyze the frequency of different values

Count the number of dots for each value. The values in the range of 6 - 8 have a relatively high frequency. Also, the frequency of 1 or 2 texts is not the same as the frequency of 11 or 12 texts.

Answer:

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