Gas Mileage The table shows the gas mileages (in miles per gallon) of eight cars with and without using a fuel additive. At a = 0.10, is there enough evidence to conclude that the additive improved gas mileage? Assume the populations are normally distributed.Car1 2 3Gas mileage (without ...
Of course, all of this is silly. Miles per gallon is a useful measure if that is the only fuel that you are putting into your car, because then it gives you an indication of how much it would cost you to drive. But electricity is not free. Probably a better measure would be cents ...
The miles per gallon meter comprises an element sensitive to the instantaneous value of petrol flow rate, a system for producing the quotional of the flow rate divided by the speed, and a system (1) for displaying this quotient. The flow rate sensor is a membrane (13) subjected to the ...
Menzie, if you wanted to do something cheeky you could do a comparison graph between the price of gas and the price of milk. I used to think that gas at more than $4 a gallon was the sign that things were about to fall apart. Now, because my nominal spending baseline has been shift...
There are a lot of Americans who must travel more than 45 miles per day for their jobs. And as for many, there is not enough public transportation. Because of the heavy traffic, roads are becoming more and more crowded. While modern cars are more fuel-efficient, the improvement is not ...
Can you combine trips? The way people drive decides how much fuel they save. Careful drivers may get 20 percent more miles per gallon than normal drivers. They could get 50 percent more miles per[translate] aThere are more than 100 million cars in the United States. A normal car gets le...
They're powerful, use relatively cheap fuel, and can propel a car 40 miles on a single gallon. But they've never really caught on in the U.S., where memories of 1970s-era soot-belching diesel cars still linger. 多年来,柴油引擎是愤怒在欧洲。 他们是强有力,用途相对地便宜的燃料,并且...
Almost one full year ago, I built myself an experimental electric bike to see what all the hype was about. As a profanely vocal proponent of muscle-only transportation, I was skeptical of the idea at first. But in the spirit of a good experiment, I decid
