In an experiment to determine the effects of outside temperature on the emissions of diesel trucks, 10 trucks were run at temperatures of 40F and then again at 80F. The emissions of each truck at the two temperatures are presented in the table below. 40F 876 778 739 776 765 803 798 724 811 819 80F 804 803 740 640 659 788 813 694 754 809 Can you conclude that the mean emissions are higher at 40F?
