Question

100 surnames were randomly picked up from a local telephone directory and a frequency distribution of the number of letters in the English alphabet in the surnames was found as follows: | Number of letters | Number of surnames | |-------------------|--------------------| | 1 - 4 | 6 | | 4 - 6 | 30 | | 6 - 8 | 44 | | 8 - 12 | 16 | | 12 - 20 | 4 | (i) Draw a histogram to depict the given information. (ii) Write the class interval in which the maximum number of surnames lie.

The frequency distribution: Marks 0-20, 20-40, 40-60, 60-100; Number of Students 10, 15, 20, 25 has been represented graphically as follows: Do you think this representation is correct? Why?

Following is the frequency distribution of total marks obtained by the students of different sections of Class VIII. Marks 100 - 150, 150 - 200, 200 - 300, 300 - 500, 500 - 800; Number of students 60, 100, 100, 80, 180. Draw a histogram for the distribution above.

The marks obtained (out of 100) by a class of 80 students are given below: Marks 10 - 20, 20 - 30, 30 - 50, 50 - 70, 70 - 100; Number of students 6, 17, 15, 16, 26. Construct a histogram to represent the data above.
