Question: Air pistols generating more than 6 ft lbf (8.1 J) and air rifles generating more than 12 ft lbf (16.2 J) of muzzle energy are legally termed ''specifically dangerous firearms''. As a result, ownership of these air rifles requires the possession of a Firearm Certificate (FAC); however, ownership of such air pistols is prohibited as they are defined as ''Prohibited Weapons'' under Section 5 of the Firearms Act 1968.

Question: Much like downhill, the other of the two ''speed'' events in alpine skiing, a super-G course consists of widely set gates that racers must pass through. The course is set so that skiers must turn more than in downhill, though the speeds are still much higher than in giant slalom (hence the name). Each athlete only has one run to clock the best time. In the Olympics, super-G courses are usually set on the same slopes as the downhill, but with a lower starting point. are there two runs in the olympic super g

Answer: no

Question: The MSE is the second moment (about the origin) of the error, and thus incorporates both the variance of the estimator and its bias. For an unbiased estimator, the MSE is the variance of the estimator. Like the variance, MSE has the same units of measurement as the square of the quantity being estimated. In an analogy to standard deviation, taking the square root of MSE yields the root-mean-square error or root-mean-square deviation (RMSE or RMSD), which has the same units as the quantity being estimated; for an unbiased estimator, the RMSE is the square root of the variance, known as the standard deviation. is root mean square error the same as standard deviation

OPTIONS:
- no

yes
