The tally chart shows the marks that students in a class received in a mathematics test. Using the information from the tally chart, complete the frequency table.

Each tally mark counts for one. And four tally marks with a line through them count for five. This means that, for the first group with marks from five to nine, we have a tally of five and four. Five plus four is equal to nine. Therefore, nine pupils scored between five and nine marks.

For the second group, we have tally marks showing five, five, and four. Five plus five is equal to 10. Adding four to this gives us 14. Therefore, 14 students scored between 10 and 14 marks. The third group shows tallies of five, five, and two. Five plus five plus two is equal to 12. Therefore ,12 students scored between 15 and 19 marks.

In the penultimate group, there were tallies of five, five, five, and one. These add up to 16. Therefore, 16 students scored between 20 and 24 marks. Finally, the last group has tallies of five and one. Five plus one is equal to six. Therefore, six students scored between 25 and 29 marks in the test.

The missing numbers in the frequency table were nine, 14, 12, 16, and six, respectively.
