An oil company wishes to study the effects of four different gasoline additives on mean gasoline mileage. The company randomly selects four groups of six automobiles each and assigns a group of six automobiles to each additive type (W, X, Y, and Z). Here all 24 automobiles employed in the experiment are the same make and model. Each of the six automobiles assigned to a gasoline additive is test driven using the appropriate additive, and the gasoline mileage for the test drive is recorded.
d) What is the test statistic?
e) What is the critical value?
f) What is the between treatment degrees of freedom?
g) What is the test result? (Reject Ho / Fail to reject Ho).
h) Interpret the result in the context.

A major oil company has developed a new gasoline additive that is supposed to increase mileage. To test this hypothesis, ten cars are randomly selected. The cars are driven both with and without the additive. The results are displayed in the following table. Can it be concluded, from the data, that the gasoline additive does significantly increase mileage? Let d = (gas mileage with additive)–(gas mileage without additive). Use a significance level of a = 0.01 for the test. Assume...

Calculate revenue. Revenue is the quantity sold times the price for the product. The quantity sold will be the smaller of the quantity supplied or the quantity demanded. (You can't sell more than you are willing to make even if the market demands a higher quantity. Likewise you can't sell more than is demanded even if you are willing to supply more than the quantity demanded.) You will need to calculate which of these values is smaller because quantity demanded...
Refers to the tables above, then answer the following questions: 1) For the individual tests (pairwise comparisons), based on the p-values and an adjusted significance level of 0.0167, should the null hypothesis be rejected or not? (Please include 3 answers, one for each comparison.) 2) What is the conclusion for all tests? That is, which groups are different from each other (if any)?
