Hello there! Here are your answers:
Does Kerri's dot plot match the data in the tally table? No.
Look at any of the hours on the chart vs dot plot. Let's take 4 for example. In the tally table, there are 6 class mates. In the plot, there are 3. So no, it is not the same.
The answers for the other problems are in this order (since it's the number of circles on the dot plot at the given hour):
5 - classmates spent 3 hours at the park
3 - classmates spent 4 hours at the park
6- classmates spent 5 hours at the park
4 - classmates spent 6 hours at the park
I hope this was helpful and let me know if you need more help! :) Have a great day! :)
