So how you wold do this problem, would be to count how many numbers fit into each category and type in that value in the according box.
So for 35-44 you would have 1 because only 1 of the values is between 35 and 44.
For 45-54 you would have 19 because there are 19 values that fit into that category.
Just continue that trend for the rest of the categories and you will have your answer!
