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: 

(i) Draw a histogram to depict the given information. 

(ii) Write the class interval in which the maximum number of surnames lie.

(i) Histogram of the given data, 

A random sample of 100 surnames was taken from a local phone book, and the frequency distribution of the letters in the English alphabet was found to be as follows:

On the x-axis, we'll plot the total number of letters, and on the y-axis, the percentage of surnames that occur every two letters.

For the y-axis, we will select a suitable scale of 1 unit Equals 4 surnames.

here classes are continued so we draw the histogram easily

(ii) Write the class interval in which the maximum number of surnames lie:

The  class interval in which the maximum number of surnames lie is 6 - 8.
