Answer 2

Step-by-step explanation:

Concentration of

sulphur dioxide (in ppm) Frequency

0.00 - 0.04 4

0.04 - 0.08 9

0.08 - 0.12 9

0.12 - 0.16 2

0.16 - 0.20 4

0.20 - 0.24 2

Total 30

(i) The figure above is the grouped frequency distribution.

(ii) The number of days for which concentration of SO

2

is more than 0.11→0.12−0.16,0.16−0.20,0.20−0.24

∴ Total number of days =2+4+2=8 days.
