A tournament organizer recorded the number of people in different age groups who participated in the archery tournament. He then created the following histogram:

Histogram with title Tournament Participants, horizontal axis labeled Age Group (year) with bins 0 to 19, 20 to 39, 40 to 59, and 60 to 79 and vertical axis labeled Number of People with values from 0 to 60 at intervals of 10. The first bin goes to 30, the second goes to 50, the third goes to 40, and the last goes to 10.

Which of the following statements best compares the height of the bars of the histogram? (2 points)

There are more participants in the 20−39 age group than in the 0−19 and 60−79 groups combined.
There are more participants in the 20−39 age group than in the 40−59 and 0−19 groups combined.
There are twice as many participants in the 40−59 age group than in the 60−79 age group.
There are twice as many participants in the 0−19 age group than in the 60−79 age group.

visual copy of the graph: https://us-static.z-dn.net/files/dbe/e99b0b3a27a9ee3137fcd8b0ea961088.jpg the histogram tells us the # of participants in each age group. ex: the group "ages 0-19" has 30 people in it, so that tells us 30 people are between ages 0-19. following the logic: simply look at each answer choice and use the graph to see whether it's true or not. starting with the first choice: "There are more participants in the 20−39 age group than in the 0−19 and 60−79 groups combined." ---> to see whether this is true, look at how tall the graph is in the 20-39 group then add (# of people in the 0-19 group) + (# of people in the 60-79 group) and see whether this total is greater than the 20-39 group or not. repeat with the other choices until you get a true statement.
