Which value is the mean CO emission (g/km)?

Explanation:
The mean emission is the average of all the CO emissions in the data set. You find it by adding up every CO emission value and dividing by how many measurements there are. This single number represents the overall level of emissions across the cars studied. In this question, the data set given yields 0.246 g/km as that average. The mean is a useful summary of central tendency, but keep in mind it can be influenced by very high or very low values.
