Question: In an experiment to determine the effect of ambient temperature on the emissions of oxides of nitrogen (NO x ) of diesel trucks, 10 trucks

In an experiment to determine the effect of ambient temperature on the emissions of oxides of nitrogen (NO_x) of diesel trucks, 10 trucks were run at temperatures of 40°F and 80°F. The emissions, in ppm, are presented in the following table. Truck 40°F 80°F 0.8347 0.8152 0.7532 0.7652 0.8557 0.8426 0.7971 0.9012 0.7854 0.7643 0.8195 0.7836 0.8629 0.8827 0.74

Can you conclude that the mean emissions differ between the two temperatures?
