MCQ

Choose the correct answer from the given four options: Consider the following distribution:

Marks obtained	Number of students
More than or equal to 0	63
More than or equal to 10	58
More than or equal to 20	55
More than or equal to 30	51
More than or equal to 40	48
More than or equal to 50	42

the frequency of the class 30-40 is:

✓
3
B
4
C
48
D
51

✓

Answer

Correct option: A.

3

a. 3
Solution:

Marks obtained	Number of students
0-10	(63 - 58) = 5
10-20	(58 - 55) = 3
20-30	(55 - 51) = 4
30-40	(51 - 48) = 3
40-50	(48 - 42) = 6
50...	42 = 42

Hence, frequency in the class interval 30-40 is 3
