Transcript

Ex 14.1, 7 To find out the concentration of SO2 in the air (in parts per million, i.e., ppm), the data was collected for 30 localities in a certain city and is presented below. Find the mean concentration of SO2 in the air. Mean(π‘₯ Μ…) = (βˆ‘β–’π‘“π‘–π‘₯𝑖)/(βˆ‘β–’π‘“π‘–) π‘₯ Μ… = 2.96/30 = 296/3000 = 98.67/1000 = 0.0986 = 0.099 Mean concentration of SO2 in the air is 0.099 ppm
