Use the following example to address questions 1-10:

A consumer is interested in comparing gas mileage between three different car manufactures. The researcher finds data at fueleconomy.gov and uses this to compare cars from 3 different manufacturers with the data presented below:

A	B	C
22	23	26
24	26	33
31	30	36
28	29	35
27	25	32

Using the level of alpha=0.05 the conclusion gleaned from the ANOVA output in the practical sense (not a post hoc analysis) indicates that:

Select one:

a. The mean MPG of manufacture A is greater than B/C

b. At least one mean MPG is different

c. The mean MPG of all three manufacturers can be considered equal

d. The mean MPG of manufacture C is statically greater than A/B
