Detailed Solution

Given, 69, 48, 84, 58, 48, 73, 83, 48, 66, 58, 84, 66, 64, 71, 64, 66, 69, 66, 83, 66, 69, 7181, 71, 73, 69, 66, 66, 64, 58, 64, 69, 69.
To create a frequency distribution table, arrange the data in the correct order, then count the items and write the number of times they appear.
Ascending order is
[48, 48, 48, 58, 58, 58, 64, 64, 64, 64, 66, 66, 66, 66, 66, 66, 66, 69, 69, 69, 69, 69, 69, 71, 71, 71, 73, 73, 81, 83, 83, 84, 84]
Count the scores, 48 comes 3 - times, 58 comes 3 - times, 64 comes 4 - times, 66 comes 7 - times, 69 comes 6 - times, 71 comes 3 - times, 73 comes 2 - times, 81 comes 1 - times, 83 comes 2 - times, 84 comes 2 - times.
Frequency distribution table is
