One advantage the Athens had was that they constructed massive walls all the way from the city to its seaport Piraeus. This allowed them to remain inside the city

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 Second Egyptian–Ottoman War or Second Turko–Egyptian War lasted from 1839 until 1841 and was fought mainly in Syria‚ whence it is sometimes referred as the (Second) Syrian War.

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.

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

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

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.
