Step 1 :Extract the CO2 emissions data from the table: \(\{154, 146, 138, 159, 138, 130, 146, 146, 192, 122, 175, 140, 146\}\)
Step 2 :Calculate the mean of CO2 emissions: \(\frac{154+146+138+159+138+130+146+146+192+122+175+140+146}{13} \approx 148.62\)
Step 3 :Calculate the standard deviation of CO2 emissions: \(\sqrt{\frac{(154-148.62)^2+(146-148.62)^2+\cdots+(146-148.62)^2}{12}} \approx 17.75\)
Step 4 :\(\boxed{\text{The mean CO2 emissions is approximately 148.62 and the standard deviation is approximately 17.75}}\)
