question 6

Explanation:

Step1: Count data in 0 - 9.9

Count how many values from the data - set fall within the 0 - 9.9 range. By going through the data, we find the values 1.2, 1.6, 5.8, 8.2. So the frequency for the 0 - 9.9 class is 4.

Step2: Count data in 10 - 19.9

Count the values in the 10 - 19.9 range. We have 12.5, 18.7. So the frequency for the 10 - 19.9 class is 2.

Step3: Count data in 20 - 29.9

Find values in the 20 - 29.9 range: 21, 21.7, 22, 23.6, 25.3, 26.1, 26.7, 26.9. The frequency for the 20 - 29.9 class is 8.

Step4: Count data in 30 - 39.9

Identify values in the 30 - 39.9 range: 30.2, 30.8, 31.6, 33.2, 34, 34.7, 34.8, 37, 37.3, 39.2. The frequency for the 30 - 39.9 class is 10.

Step5: Count data in 40 - 49.9

Find values in the 40 - 49.9 range: 40, 40.3, 43.1, 43.5, 43.9, 46.7, 48.3, 49.5. The frequency for the 40 - 49.9 class is 8.

Answer:

Class	Frequency
10 - 19.9	2
20 - 29.9	8
30 - 39.9	10
40 - 49.9	8
