A study was conducted to find the concentration of Sulfur dioxide (SO2) in a cityatmosphere in ppm. The information received in 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, 0.04Based on this information,(i) Make a grouped frequency distribution table for this class intervals as 0.00-0.04, 0.04-0.08… and so on.(ii) For how many days will the concentration of SO2be more than 0.11 ppm? |
