Q. 5. A study was conducted to find out the concentration of sulphur dioxide in the air inparts per million (ppm) of a certain city. The data obtained for 30 days is as follows:
0.03 0.08 0.08 0.09 0.04 0.17
0.16 0.05 0.02 0.06 0.18 0.20
0.11 0.08 0.12 0.13 0.22 0.07
0.08 0.01 0.10 0.06 0.09 0.18
0.11 0.07 0.05 0.07 0.01 0.04
(i) Make a grouped frequency distribution table for this data with class intervals as 0.00 - 0.04, 0.04 - 0.08, and so on.
The lowest value of the concentration of sulphur dioxide in the air is 0.01 ppm
The highest value of the concentration of sulphur dioxide in the air is 0.22 ppm
The representation of the given data in the form of a frequency distribution table is as follows.
