The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4] The parameters used are:
The handbook was originally published in 1928 by the Chemical Rubber Company (now CRC Press) as a supplement (Mathematical Tables) to the CRC Handbook of Chemistry and Physics.

The Bautz–Morgan classification was developed in 1970 by Laura P. Bautz and William Wilson Morgan to categorize galaxy clusters based on their morphology. [1] It defines three main types: I, II, and III. Intermediate types (I-II, II-III) are also allowed. A type IV was initially proposed, but later redacted before the final paper was ...
Michael Danos and Johann Rafelski edited the Pocketbook of Mathematical Functions, published by Verlag Harri Deutsch in 1984. [14] [15] The book is an abridged version of Abramowitz's and Stegun's Handbook, retaining most of the formulas (except for the first and the two last original chapters, which were dropped), but reducing the numerical tables to a minimum, [14] which, by this time, could ...
In 1970, he was an invited speaker at the International Congress of Mathematicians in Nice. [3] From 1965 to 1982 he was an editor for the Journal of Differential Geometry and from 1966 to 1969 an editor for the Transactions of the American Mathematical Society. In 1979 he co-found the TeX Users Group and become its first president. [4]
existed, Canary recused herself anyway to avoid even an appearance of impropriety. I, Louis V. Franklin, Sr., was appointed Acting U.S. Attorney in the case after Charles Niven retired in January 2003.
The model, first published in 1970 and updated in 1971 and 1977, is based on spacecraft drag data, and is primarily used in spacecraft modeling and related fields. A common assumption while using the Jacchia Model is that the atmosphere rotates with the Earth as a rigid body. The statistical accuracy of the Jacchia Model is 15%.
Sisterhood Is Powerful: An Anthology of Writings from the Women's Liberation Movement is a 1970 anthology of feminist writings edited by Robin Morgan, a feminist poet and founding member of New York Radical Women. [1] It is one of the first widely available anthologies of second-wave feminism.
