A group of 23 students participated in a math competition. Their scores are below: Score (points) 20–29 30–39 40–49 50–59 60–69 Number of Students 4 7 5 4 3 Would a dot plot or a histogram best represent the data presented here? Why? Histogram, because a large number of scores are reported as ranges Histogram, because a small number of scores are reported individually Dot plot, because a large number of scores are reported as ranges Dot plot, because a small number of scores are reported individually

    @Vocaloid sorry, one more. Is this C? Which of the following questions is a statistical question? What is the top-selling board game? In what aisle are the board games located in the local store? How many board games require a deck of cards to play?<<< How many board games have you played in the past month?
