Answer 1

Step-by-step explanation:

Given A class test was held for 40 students and their marks out of 60 are as under 4,7, 9, 8, 9, 10, 8, 15, 16, 33, 15, 23, 27, 35, 38, 18, 20, 25, 28, 32, 43, 48, 36, 39, 24, 42, 45, 47, 28, 19, 39, 29, 34, 49, 50, 23, 34, 42, 32, 18. Construct a grouped frequency distribution table.

• We need to construct a grouped frequency distribution table.
• So the marks of 40 students are  
• 4,7, 9, 8, 9, 10, 8, 15, 16, 33, 15, 23, 27, 35, 38, 18, 20, 25, 28, 32, 43, 48, 36, 39, 24, 42, 45, 47, 28, 19, 39, 29, 34, 49, 50, 23, 34, 42, 32, 18.
• So the class size will be 10 like 0 to 10 up to 50 to 60
• So the table can be written as follows:
•   Marks                                     Number of students
•   0 – 10                                                  6
•  10 – 20                                                 7
•  20 – 30                                                 9
•  30 – 40                                                10
•  40 – 50                                                 7
•  50 – 60                                                 1
•                                                              40
•   Therefore total number of students is 40
