Answer:
To create a frequency distribution table, we need to group the weights into intervals and count the number of students in each interval. One common interval size is 5 kilograms.
Class interval | Tally | Frequency
--- | --- | ---
30-34 | | 0
35-39 | || 4
40-44 | ||| 6
45-49 | || 3
50-54 | | 2
55-59 | | 0
60-64 | | 1
65-69 | | 2
To create the table, we first create the class intervals by grouping the weights into groups of 5. Then, we use tally marks to count the number of weights that fall into each interval. Finally, we count the tally marks to find the frequency for each interval.
For example, there are 4 students with weights between 35 and 39 kilograms, so the frequency for that interval is 4. There are 6 students with weights between 40 and 44 kilograms, so the frequency for that interval is 6. And so on for the other intervals.
