Probability Term Paper Example | Topics and Well Written Essays - 1750 words

Probability - Term Paper Example Statistics use assumption on population distribution to estimate population values based on sample values (Kemp & Kemp 257-66). Probability distributions functions or simply distribution functions are used (Soong 39-41). The distribution function associates a variable value with a probability (Soong 39). This can take the form Fx(x) =P(Xx) where the lowercase x refers to a specific value of a variable. Probability distribution functions have shapes represented by the mathematical equations. The areas under the curves or distribution functions are associated with probabilities. In business statistics, some of the distribution functions that are often used are the Z-statistics, t-statistics, chi-square distribution, and the F-statistics (Kemp & Kemp 47-297). There is also an option to use what statisticians call as the non-parametric statistics (Kemp & Kemp 298-315). The choice of what distribution functions to use are determined by convention or typical practice and theory. For example, in estimating the population mean, it is assumed that the sample mean converge to the population mean through repetition of sampling procedures or if the population is large. Thus, in estimating the mean, statistics usually makes the assumption based on a normal distribution. Although several distribution functions are used in statistics, in this work we focus our sights on three: the z-statistics, the t-statistics, and the chi-square statistics. Figure 1 captures a standard normal distribution function. The standard normal distribution associates a value of a variable with probability. For example, the probability that the value of the variable is between a very low number and high number can be represented by 100%. In the language of statistics, this take s the form P (-< x < +) = 1 or 100%. In other words, this means that in a

Described in the Seneca Falls - Essay Example †Now, in view of this entire disfranchisement of one-half the people of this country, their social and religious degradation,—in view of the unjust laws above mentioned, and because women do feel themselves aggrieved, oppressed, and fraudulently deprived of their most sacred rights, we insist that they have immediate admission to all the rights and privileges which belong to them as citizens of these United States.† Above is the main objective of the feminist groups at the convention. Under it states the details of such rights to be received by women; the right to suffrage, equal opportunities, social status, etc., giving emphasis to â€Å"All men are created equal†¦Ã¢â‚¬  in the Declaration of Independence, which they explained the term ‘men’ is being pertained to people and not gender specific. The convention succeeded in their objective to open the eyes of society to the injustices received by women that time. Uniting powerful elements at the convention such as gathering groups of antislavery, reformists and radical Quakers acted as one of the most important things that highlight the event that was one of the factors the convention became a success. This provoked one of the greatest rebellions in history of the modern times. The convention at the Seneca Falls only sparked the beginning of the struggle of women towards their thirst for equality and gave birth to more feminist groups to take part in their journey. Led by a number of famous and reputable women like Elizabeth Cady Stanton, a woman rights pioneer, the Declaration of Sentiments became a success. â€Å"That all laws which prevent woman from occupying such a position in society as her conscience shall allow, or which place her in a position inferior to that of man, are contrary to the great law of nature, and therefore of no force or authority.† Above is one of the most appealing resolutions presented at the convention. Although this may not hold true to all women since the â€Å"coloured† still
