Answer:
1.I think the dot plot was the right decision because we are trying to go over specific data.For instance bar graphs are good if you are trying to get data on things that are in ranges like 1-3 and 4-6 but when you have things like this where he is trying to show each value its better to use a dot plot
2. 16 students are in this class (you can just count the dots to get this answer)
3. the class is a adult swim class-yes,this class ranges between 18 year olds to 32 year olds which are all legally adults
Half the students are between 2 and 3 years old-no,the minimum or youngest age that this set has is 18 years old which is still alot of a higher value than 2 or 3
Step-by-step explanation:hope this makes sense and helps you
