Question

In an experiment to determine the effect of ambient temperature on the emissons of oxides of nitrogen (

NOx

) of diesel trucks, 

10

 trucks were run at temperatures of 

40°F

 and 

80°F

. The emissions, in parts per billion, are presented in the following table.

Send data to Excel

Let

μ1

 represent the mean emission at 

40°F

 and 

=μd−μ1μ2

.
Can you conclude that the mean emission differs between the two temperatures? Use the 

=α0.05

 level of significance and the TI-84 Plus calculator to answer the following.

p value ?

do we reject?

is there enough evidence :?
