The dot plot represents the prices of different brands of chocolate bars. each dot represents a different brand of chocolate. how many brands are included in this data set? a. 18 b. 19 c. 20 d. 21 e. 22

The correct answer option is E. 22

Step-by-step explanation:

We are given a dot plot which represents the prices of different brands of the chocolate bars.

Given that each dot on the dot plot represents a different brand of the chocolate, we can find the total number of chocolate brands that are included in the data set.

To find the total number of chocolate brands, we just need to add the number of dots represented against each price to get:

Total number of chocolate brands = 1 + 4 + 3 + 5 + 2 + 3 + 2 + 1 + 1 = 22

Therefore, 22 different brands are included in this data set.
