 Hello and welcome to the session. In this session we discussed the following question which says given below is a cumulative frequency table extract a frequency table from the above. Let's see the solution now. Now we need to make the frequency table. So for this in this table we will make the interval of the marks obtained by the student and the number of students. Now in this cumulative frequency table we have that the marks below 10 are obtained by 20 students. So for below 10 we would make the interval as 0 to 10 and the number of students getting the marks between 0 and 10 would be 20. Now consider the cumulative frequency table again in this. Next we have that below 20 we have the number of students are 25. Now that we have already made the interval of 0 to 10 so for below 20 we will make the interval as 10 to 20 and in this the number of students would be given by subtracting 20 from 25 so we get 5. Number of students getting the marks between 10 to 20 are 5. Now next we have below 30 number of students are 35. So for below 30 the interval would be 20 to 30 and the frequency for this interval that is the number of students getting the marks between 20 and 30 would be obtained by subtracting 25 from 35. 35 minus 25 is 10 so the number of students getting the marks between 20 to 30 is 10. Then next we have below 40 the number of students are 47 and for below 40 the interval would be 30 to 40 and the frequency for this would be obtained by subtracting 35 from 47 so 47 minus 35 gives us 12 so the number of students getting the marks between 30 and 40 is 12 then next below 50 the number of students are 52 so the interval for below 50 would be 42, 50 and the number of students for this interval would be obtained by subtracting 47 from 52 and this would give us 5 so the number of students getting the marks between 40 and 50 are 5 for below 60 the number of students are 60 so for below 60 the interval would be 52, 60 and its frequency would be obtained by subtracting 52 from 60 so 60 minus 52 gives us 8 so the number of students getting the marks between 50 and 60 would be 8 so this is the frequency table extracted from the given cumulative frequency table so this completes the session hope you have understood the solutions for this question
