Hit probability

Hi group, I'm looking for an method to calculate the hit probabilty for the first shot fired with a rifle. From this rifle and its ammonition are measured in previous sessions a mean and a standard deviation. Also the target size and distance are know. Can anyone give me a tip (preferable in a

I think I may have to be clearer about what I have and what I want. I am sampling names (for a mail survey) from a database of registered voters. I want the names to be distributed geographically in proportion to the population of the 21 counties of New Jersey. I have 21 pairs of numbers: for

The price of ECHIP is intended to discourage its use as "just a computer program," which is quite frankly a dangerous practice. The problem that ECHIP deals with is the preparation of an engineer or scientist to treat real experimental problems, which can only come with a modest understanding

It is a form of the bivariate normal. If x is the distance from the aim point, then the density is (x/s^2)exp(-x^2/(2s^2)), and s is the common standard deviation. There is substantial data to show that this is a reasonable description of the pattern for small arms fire. Shareef Siddeek wrote:

Hi Clark, You maybe are aware of this, but describing the 'location' of an interaction is not as simple as it might seem at first glance. For example, in a 2x2 ANOVA it is not possible to locate an interaction in any one cell, or even any two or three cells: the interaction involves a
