The following bar graph represents the data for different sizes of shoes worn by the students in a school. Read the graph and answer the following questions.
Scale: 1 unit length = 50 students
A. Find the number of students whose shoe sizes have been collected.
B. What is the number of students wearing shoe size 6?
C. What are the different sizes of the shoes worn by the students?
D. Which shoe size is worn by the maximum number of students?
E. Which shoe size is worn by minimum number of students?
F. State whether true or false:
The total number of students wearing shoe sizes 5 and 8 is the same as the number of students wearing shoe size 6.
(A) 1300
Total number of students whose shoe sizes have been collected = sum of the number of students wearing different sizes of shoes
From the above graph, it can be observed that the number of students wearing shoes of size 4 = 250
From the above graph, it can be observed that the number of students wearing shoes of size 5 = 200
From the above graph, it can be observed that the number of students wearing shoes of size 6 = 300
From the above graph, it can be observed that the number of students wearing shoes of size 7 = 400
From the above graph, it can be observed that the number of students wearing shoes of size 8 = 150
Therefore, total number of students whose shoe sizes have been collected = 250+200+300+400+150 = 1300
(B) 300
From the above graph, it can be observed that the number of students wearing shoe size 6 is 300.
(C) Sizes are 4, 5, 6, 7 and 8.
From the graph, it can be observed that the different sizes of shoes worn by the students are 4, 5, 6, 7 and 8.
(D) Shoe size 7
From the graph, it can be observed that 400 students wear the shoes of size 7 which is the most among other shoe sizes.
(E) Shoe size 8
From the graph, it can be observed that 150 students wear the shoes of size 8 which is the least among other shoe sizes.
(F) False
From the graph, it can be observed that the total number of students wearing shoe sizes 5 and 8 = 200+150 = 350.
Also, the total number of students wearing shoes of size 6 is 300 which is not equal to the number of students wearing shoe sizes 5 and 8.
