Question

A regional package delivery company is considering changing from full-size vans to minivans. The company sampled 3 minivans from each of three manufacturers. Each minivan was driven for 5,000 miles, and the operating cost per mile was computed. The operating costs, in cents per mile, for the 9 minivans are provided in the table below:

Manufacturer 1	Manufacturer 2	Manufacturer 3
15	11	14
14	13	16
13	12	15

Compute SST, SSE, and SS total and complete the ANOVA table.

Source of Variation	Sum of Squares	df	Mean Sum of Squares	F

Total

State the null hypothesis : (Choose 1 or 2)
The treatment means are the same
The treatment means are different

State the alternative hypothesisl hypothesis : (Choose 1 or 2)
The treatment means are the same
The treatment means are different

d. What is the decision rule?

Reject H_o if F is greater than

e. What is your decision :(Choose 1 or 2)
Reject H_o
Do not Reject H_o

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 + ...
