The required histogram is attached as a picture.
Given the information on how many pages each of the 20 pupils read throughout the summer.
163, 170, 171, 173, 175, 205, 220, 220, 220, 253, 267, 281, 305, 305, 305, 355, 371, 388, 402, 431
With frequency on the y axis and class on the x axis.
we observe the histogram and make out that:
class 160 - 220 has the highest frequency of 6 students whereas
400 - 460 has the least with 2 students.
The classes between them range as follows:
220 - 280 has 5 students
280 - 340 has 4 students
340 - 400 has 3 students.
Hence the required histogram is created .
