Answers
Answer:
Classes Tally Marks Frequency
10 - 20 4 4
20 - 30 8 8
30 - 40 6 6
40 - 50 6 6
50 - 60 3 3
60 - 70 3 3
Step-by-step explanation:
Given,
The donations made by 30 houses in a locality are as under :
42, 35, 28, 12, 14, 16, 47, 50, 52, 27, 34, 42, 26, 28, 36, 15, 64, 65, 38, 40, 22, 24, 29, 31, 39, 48, 53, 62, 23, 43.
To Find,
The grouped frequency distribution with class size 10.
So,
The grouped frequency distribution table is as follows:
Classes Tally Marks Frequency
10 - 20 4 4
20 - 30 8 8
30 - 40 6 6
40 - 50 6 6
50 - 60 3 3
60 - 70 3 3
Total: 30
Hence, this is the correct grouped frequency distribution table formed.

Answer:
A grouped frequency distribution displays the scores by grouping the observations into intervals and then records these intervals in the frequency distribution table.
Step-by-step explanation:
frequency distribution, in statistics, a chart or data set is collected to show the frequency of occurrence of each possible result of a repeatable event observed many times. Simple examples exist election returns and test scores listed by percentile.
A grouped frequency distribution displays the scores by grouping the observations into intervals and then records these intervals in the frequency distribution table. The intervals in grouped frequency distribution frame are named class limits.
Here given that,
Donations made by 30 houses in a locality exist as under
42, 35, 28, 12, 14, 16, 47, 50, 52, 27, 34, 42, 26, 28, 36, 15, 64, 65, 38, 40, 22, 24, 29, 31, 39, 48, 53, 62, 23, 43.
