18. please have all 6 steps of the p method listed clearly!

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

NOx

) of diesel trucks,

trucks were run at temperatures of

40°F

and

80°F

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

Truck	40°F	80°F
1	951.6	924.1
2	836.1	862.0
3	984.1	960.6
4	937.2	837.0

Let

μ1

represent the mean emission at

40°F

and

=μd−μ1μ2

.
Can you conclude that the mean emissions are higher at

40°F

? Use the

=α0.05

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

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
