A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows : For how many days, was the concentra-tion ofsulphur dioxide more than 0.11 parts per million.

A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows : You were asked to prepare a frequency distribution table, regarding the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city for 30 days . Using this table, find the probability of the concentration of sulphur dioxide in the interval 0.12-0.16 on any of these days.

A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows : Make a grouped frequency distribution table for this data with class intervals as 0.00 - 0.04, 0.04 -0.08 and so on.

A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is a follows : (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. (ii) For how many day's was the concentration of sulphar dioxide more than 0.11 parts per million (ppm)?
