What are the main theoretical and political differences between first’ and second’ wave feminism Feminism is both an intellectual commitment and a political movement that seeks justice for women and the end of sexism in all forms. However‚ there are many different kinds of feminism. So some have found it useful to think of the women’s movement in the US as occurring in "waves" . On the wave model‚ the struggle to achieve basic political rights during the period from the mid-19th century until the

Confidence Intervals Consider the following question: someone takes a sample from a population and finds both the sample mean and the sample standard deviation. What can he learn from this sample mean about the population mean? This is an important problem and is addressed by the Central Limit Theorem. For now‚ let us not bother about what this theorem states but we will look at how it could help us in answering our question. The Central Limit Theorem tells us that if we take very many

The emergence of second-wave empires in 500 BCE coincides with the decline of earlier river societies‚ also known as first-wave civilizations‚ which were present from approximately 3500 BCE to 500 BCE. River valley societies were‚ as its name suggests‚ situated near rivers as a source of water for irrigation and everyday use. In comparison‚ second-wave empires adopted many traits from earlier civilizations and elaborated on them or completely changed them. Despite bearing some minor similarities

A study is conducted to estimate the mean cholesterol in children between the ages of 2 - 6 years of age. It also attempted to establish a correlation as to the effect family history has on the onset of the disease

Practice Problems for Confidence Intervals X ± Z σ/n ; X ± t s/n ; p ± Z (p(1-p)/n) 1. A press release issued by our university claims that West Chester students study at least as much as the national average for students at four year universities. Across the nation‚ 73 percent of all students at four year universities study at least four hours per week. Seventy percent of one hundred randomly selected West Chester students surveyed claimed to study more than four hours per week.

confidence interval on π‚ the proportion that malfunction in the population. Solution: The value of p is 12/40 = 0.30. The estimated value of σp is = 0.072. A z table can be used to determine that the z for a 95% confidence interval is 1.96. The limits of the confidence interval are therefore: Lower limit = .30 - (1.96)(0.072) = .16 Upper limit = .30 + (1.96)(0.072) = .44. The confidence interval is: 0.16 ≤ π ≤ .44. Q2.

To what extent was the Second Reich an entrenched autocracy between 1900-1914? In the years 1900-1914 there was arguably a significant move towards democracy within Germany. There were general desire for political and social reform and many wished for constitutional change. However‚ come 1914 Germany still remained nearly as autocratic as it had been back in 1900. Over this period it can clearly be shown through 3 key areas: the Constitution‚ German policy and events‚ that‚ regardless of attempted

Confidence Intervals have numerous applications for professional activities. Confidence Intervals have a wide use in defining the outcome of a particular question. The use of confidence levels are used commonly in Health‚ Business‚ Politics and Engineering venues. There are three examples that will be recognized as having real world applications regarding confidence intervals. An Empirical Test of the Black-Scholes (BS) Option pricing model exhibited the use of a confidence interval approach.

Abstract The aim was to identify the proportion of fathers having a positive experience of a normal birth and to explore factors related to midwifery care that were associated with a positive experience. Background: Research has mainly focused on the father’s supportive role during childbirth rather than his personal experiences of birth. Methods: 595 new fathers living in a northern part of Sweden‚ whose partner had a normal birth‚ were included in the study. Data was collected by questionnaires
