Answers
Frequency table is prepared below:
Step-by-step explanation:
We are given with the Monthly savings (in rupees) of 30 students of class VII below;
5, 80, 43, 90, 64, 20, 24, 30, 50, 56, 60, 6, 40, 21, 12, 8, 16, 5, 14, 35, 45, 95, 74, 63, 55, 37, 80, 20
Now, we have to Prepare a frequency distribution table with Class Intervals 0-10, 10 - 20 and so on:
Frequency distribution table shows that how many times a particular number appears in our data, i.e.;
Class interval of 0 - 10 shows that how many data values lie within this interval.
Class Interval Frequency
0 - 10 4
10 - 20 3
20 - 30 4
30 - 40 3
40 - 50 3
50 - 60 3
60 - 70 3
70 - 80 1
80 - 90 2
90 - 100 2
Total = 28
Hence, this is the required frequency table.
Answer:
class Interior frequency
0 -10 4
10 - 20 3
20 - 30 4
30 - 40 3
40 - 50 3
50 - 60 3
60 - 70 3
70 - 80 1
80 - 90 2
90 - 100 2
total = 28
