Does octane matter: Octane is a measure of how much fuel can be compressed before it spontaneously ignites. Some people believe that higher-octane fuels result in better gas mileage for their cars. The number of miles driven for various drivers until the car ran out of gas was recorded. Does high-octane fuel result in better gas mileage? Use significance level 0.05. (Paired samples).

Driver 1 2 3 4 5 6 7 8 9 10 11
87 octane 234 257 243 215 114 287 315 229 192 204 547
92 octane 237 238 229 224 119 297 351 241 186 209 562

The capacitance of an object is a measure of how much charge separation can be produced on the object by applying a voltage difference to it, or contrarily, how much voltage arises across the object as a result of a particular charge separation developing. The equation defining the capacitance is Q = C ΔV where Q is the charge separation (+Q and -Q at two different places on the capacitor), C is the capacitance, and ΔV is the potential difference....

The eigenvalue is a measure of how much of the variance of the observed variables a factor explains. Any factor with an eigenvalue ≥1 explains more variance than a single observed variable, so if the factor for socioeconomic status had an eigenvalue of 2.3 it would explain as much variance as 2.3 of the three variables. This factor, which captures most of the variance in those three variables, could then be used in another analysis. The factors that explain the...
