Question
I need the right answers this problem.
Transcribed Image Text:In an experiment to determine the effects of outside temperature on the emissions of diesel trucks, 10
trucks were run at temperatures of 40°F and then again at 80°F. The emissions of each truck at the two
temperatures are presented in the table below.
