Solution

## Step 1: Arranging numbers in ascending order Given, 16, 17, 21, 20, 16, 20, 16, 18, 17, 21, 17, 18, 19, 17, 15, 15, 19, 19, 18, 17, 17, 15, 15, 16, 17, 17, 19, 18, 17, 16, 15, 20, 16, 17, 19, 18, 19, 16, 21, and 17. Required ascending order: 15, 15, 15, 15, 15, 16, 16, 16, 16, 16, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 18, 18, 18, 18, 18, 19, 19, 19, 19, 19, 20, 20, 20. Hence, above is the required ascending order of given numbers. Step 2: Representing the given data in the frequency distribution table Hence, required frequency distribution table : Numbers Tally Marks Frequency 15 |||| 5 16 |||| || 7 17 |||| |||| | 11 18 |||| 5 19 |||| | 6 20 ||| 3 21 ||| 3 Total 40
