There must be a formula, but in the mean time there is a handy site that does it for you. [See related link below for the converter]
Standard Deviation = (principal value of) the square root of Variance. So SD = 10.
Information is not sufficient to find mean deviation and standard deviation.
Standard deviation is the square root of the variance.
One standard deviation for one side will be 34% of data. So within 1 std. dev. to both sides will be 68% (approximately) .the data falls outside 1 standard deviation of the mean will be 1.00 - 0.68 = 0.32 (32 %)
Standard deviation is a statistical concept and not applicable to concrete.
Standard deviation = square root of variance.
No. It's the number that will help you work out the percentage.
Standard Deviation = (principal value of) the square root of Variance. So SD = 10.
4.55% falls outside the mean at 2 standard deviation
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.

The standard deviation is the standard deviation! Its calculation requires no assumption.
no
The standard deviation of the population. the standard deviation of the population.
The standard deviation is 0.
