Respuesta :

I suggest writing a table with the following intervals (50-54, 55-59, 60-64 and 65-69) In the first column and in the second column write the frequency (the number of numbers in that interval).

As an example

| Interval | Frequency |
———————————-
| 50-54 | 3 |
———————————-
| 55-59 | ... |
———————————-

And so on
