oyota USA is studying the effect of regular versus high-octane gasoline on the fuel economy of its new high-performance, 3.5-liter, V6 engine. Ten executives are selected and asked to maintain records on the number of miles traveled per gallon of gas. The results are:
a. STATE THE NULL HYPOTHESIS AND ALTERNATE HYPOTHESIS
| Miles per Gallon | Miles per Gallon | |||||
| Executive | Regular | High-Octane | Executive | Regular | High-Octane | |
| Bowers | 25 | 28 | Rau | 38 | 40 | |
| Demars | 33 | 31 | Greolke | 29 | 29 | |

Seastrand Oil Company produces two grades of gasoline: regular
and high octane. Both gasolines are produced by blending two types
of crude oil. Although both types of crude oil contain the two
important ingredients required to produce both gasolines, the
percentage of important ingredients in each type of crude oil
differs, as does the cost per gallon. The percentage of ingredients
A and B in each type of crude oil and the cost per gallon are
shown.

Ethanol (C2H5OH) and gasoline (assumed to be all
octane, C8H18) are both used as automobile fuel. If gasoline is
selling for $2.25/gal, what would the price of ethanol have to be
in order to provide the same amount of heat per dollar? The density
and ΔH f
of octane are 0.7025 g/mL and −249.9 kJ/mol and the density and ΔH
f
of ethanol are 0.7894 g/mL and −277.0 kJ/mol, respectively. Assume
that the products of combustion are CO2(g) and H2O(l)....

Unleaded gasoline can be purchased with various octane ratings,
typically 87 (regular), 88-90(mid-grade), and 91-94 (premium). The
octane rating indicates how resistant the fuel is to engine knock.
If a fuel cannot withstand compression without detonating from the
heat of compression, it will cause engine knock. Engine knock is
when small pockets of the mixed air and fuel ignites after the
spark ignited the fuel-air mixture in the combustion chamber. This
reduces engine efficiency and can result in damage to...
