The standard error is calculated by dividing the actual volume by the experimental volume. This is a common technique used in the laboratory.
It is Z, except that the font used is not one of the standard ones.
Pi as a symbol was first used by the English mathematician William Jones. In 1706 he wrote that 3.14159=Euler, in 1737, used this symbol and it became the worlds standard symbol for pi after that.
Yes, in statistics, the epsilon symbol is used for maximum allowable error. http://www.liaad.up.pt/~jgama/IWKDDS/Papers/p14.pdf
The parameters of the underlying distribution, plus the standard error of observation.
The trefoil symbol, consisting of three interlocked circles, is commonly used to identify radioactive materials. This symbol serves as a warning to indicate the presence of radioactivity and the potential hazards associated with handling these materials.
The distinctive symbol used to identify radioactive materials is the trefoil symbol. It consists of three interlocked blades on a yellow background. This symbol is used to warn people of potential radiation hazards.

the sample mean is used to derive the significance level.

Standard error is the difference between a researcher's actual findings and their expected findings. Standard error measures the accuracy of one's predictions. Standard deviation is the difference between the results of one's experiment as compared with other results within that experiment. Standard deviation is used to measure the consistency of one's experiment.
This question requires care to prevent confusion, and a basic knowledge of statistics. I've seen three types of descriptive statistical error bar used: standard deviation, standard error, or confidence interval. The use of any of these indicates that each point in the graph around which error bars are placed is the mean of a set of values. The error bars then give an indication of this set of data: * Standard deviation gives an indication of the variability of the underlying set of values. * Standard error gives an indication of how close the calculated mean of the set of values is to the mean of the entire population of these values (this is dependant on the number of these values the mean is found from - the greater the number of values used, the smaller the standard error). * The condfidence interval is the range which is likely to contain the true population mean (and is thus related to the standard error). Each of these may be used depending on the data used. However, you have to be careful since the first two of these are often confused - and the type of error bar used is often not labelled at all. Hope that helped :-)
The ticker symbol for Wells Fargo stock is WFC. A ticker symbol refers to an abbreviation that is used on a stock market to identify that particular company.
Standard of deviation and margin of error are related in that they are both used in statistics. Level of confidence is usually shown as the Greek letter alpha when people conducting surveys allow for a margin of error - usually set at between 90% and 99%. The Greek letter sigma is used to represent standard deviation.
It is the standard error.
