Question 1183616: In one experiment, a number of cars with different characteristics are run on a test track at a speed of between 70 and 80 kilometers per hour. A number of properties are measured and the average consumption of fuel is registered.
The variables included in the analysis are
- The car's average consumption in liters / mile
- Weight of the car in kilograms (Weight)
- The car's average speed during the test in km / h (Average speed)
- Whether the car was front-wheel drive, rear-wheel drive or four-wheel drive (Front-wheel drive, Rear-wheel drive, Four-wheel drive)
The information is then entered into Excel and a regression analysis is performed, with the following results:
Coffecients:
Constant: 0,3067
Weight: 0,0001
Average speed:0,0023 with t: 1,1494
Rear wheel drive:0,0151
Four-wheel drive:0,0586
ANOVA
F: 10,4011
p -vaule for F: 4,77726E-08 = 0,0000000477726
a)Interpret the equation and it's components in words
b) Interpret the completed F-test. Also set out the current hypotheses and describe what they mean.
c) Interpret the average t-test performed for Average Speed. Also set out the current hypotheses and describe what they mean.

You can put this solution on YOUR website! .
The longer a post is, the lesser a chance that somebody will read it.
It is the LAW on how the contemporary people take reading.
Therefore, normal Math problem is 3 - 4, maximum 5 lines of standard text.
Everything longer is not a Math problem.
