What is the 95% z-score?

Answers

Answer 1

When utilizing a 95 percent confidence level, the essential z-score values are between -1.96 and +1.96 standard deviations.

In order to determine a z-score, use the formula z = (x-μ)/σ, where x is the raw score, is the community mean, and is the community standard deviation. The z-score, as demonstrated by the calculation, is the raw score less the population mean divided by the population's standard deviation.

You only have a 5% probability of being wrong with a 95 percent confidence interval. There is a 10% risk that you could be incorrect with a 90% confidence interval. In comparison to a 95% confidence interval, a 99 percent confidence interval would be larger (for example, plus or minus 4.5 percent instead of 3.5 percent).

Read the excerpt from President Ronald Reagan’s Address at Moscow State University.

But progress is not foreordained. The key is freedom—freedom of thought, freedom of information, freedom of communication. The renowned scientist, scholar, and founding father of this university, Mikhail Lomonosov, knew that. "It is common knowledge," he said, "that the achievements of science are considerable and rapid, particularly once the yoke of slavery is cast off and replaced by the freedom of philosophy." You know, one of the first contacts between your country and mine took place between Russian and American explorers. The Americans were members of Cook's last voyage on an expedition searching for an Arctic passage; on the island of Unalaska, they came upon the Russians, who took them in, and together with the native inhabitants, held a prayer service on the ice.

Read the passage.

(1) Ask young people today if they know of anyone who has had smallpox, and they might ask, "What’s smallpox?” (2) That is because this disease was eradicated from the planet decades ago, thanks to vaccinations. (3) Despite the obvious effectiveness of vaccination, opponents of this procedure argue that humans are better off fighting diseases on their own without adding anything potentially harmful to their bodies. (4) Still, the American Academy of Pediatrics says that vaccines can be 99 percent effective, and the Centers for Disease Control claims that, over a 10-year period, vaccines allowed 322 million children to avoid illnesses. (5) So the next time someone tells you that vaccines are poisoned apples that will lead to a fate like Snow White’s, counter their argument with the facts. (6) The bottom line is that vaccines are safe to use and save lives.

Analyse the impact that the increasing number of social grants may save on the:
3.3.2 Teen mothers​

Answers

Answer and Explanation:

Social grants are government programs that provide economic assistance to individuals who are unable to work, or who are experiencing financial difficulties. This type of program is very important for poor communities with a high low quality of life.

Among the individuals who can be helped with a social grant, we can mention the adolescent mothers as one of the biggest beneficiaries. This help that the government provides for these mothers can meet their needs and the needs of the child they are in and care for the children for a set time, promoting a delightful time in life. In this way, mothers achieve safety and care, which has saved many mothers and babies across the country and freed these mothers from placing children and themselves in depressing and dangerous situations.

There are many teen mothers who need grants to survive and take care of their children hence, more grants will ensure that these mothers and their children are properly catered to.

What are Grants?

Grants are monies given to people without the requirement for them to pay back.

Grants can be given by governments, organizations, or individuals. When teen mothers are taken care of, it reduces the chances that their children will become juvenile delinquents.

What is Shirley Chisholm's overall purpose in her speech?
A. to discredit the other candidates running for the Democratic nomination
B. to persuade people that she is the right choice for the Democratic nomination
C. to convince people that she has overwhelming support for the Democratic
nomination
D. to pressure people to vote for her for the Democratic nomination

Answers

B. to persuade people that she is the right choice for the Democratic nomination

To persuade people that she is the right choice for the Democratic nomination is Shirley Chisholm's overall purpose in her speech. Hence, option D is correct.

What is the main idea of Chisholm's speech?

The need for the ERA served as the speech's main theme. Similar to the ERA, a constitutional amendment would provide federal protection and supersede any state laws that would encourage discrimination.

In the 95th and 96th Congresses, from 1977 to 1981, Chisholm held the position of Secretary of the Democratic Caucus. Chisholm campaigned to increase possibilities for citizens in inner cities throughout her time in Congress. She supports raising the amount spent on social services including education and healthcare.

If there were still any labor regulations that only applied to women, their revision or repeal would give them access to better-paying employment in manufacturing. More options for women in public graduate and vocational institutions would also generally increase their chances of finding better employment.

Thus, option D is correct.

Answers

Answer:

You have 72 cubic feet of space for your toys.

Explanation:

What we need to find here is the volume of the toy bin. Volume can be defined as a three-dimensional space that is enclosed by a boundary. In this case, it would be the walls, bottom, and lid of the bin. The formula to calculate volume is length X width X height, that is, the multiplication of the three dimensions. According to the instructions, we have the following dimensions: 6 x 4 x 3 = 72. Thus, we can say that we have 72 cubic feet of space for the toys in the bin.

The Mississippian culture was a Native American civilization that flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 CE to 1600 CE, varying regionally. It was known for building large, earthen platform mounds, and often other shaped mounds as well.

Mississippian culture was not a single "tribe," but many societies sharing a similar way of life or tradition. Mississippian peoples lived in fortified towns or small homesteads, grew corn, built large earthen mounds, maintained trade networks, had powerful leaders, and shared similar symbols and rituals.

Unlike contemporary people, Mississippian people spent much of their lives outdoors. Their houses were used mainly for shelter from inclement weather, sleeping in cold months, and storage. These were rectangular or circular pole structures; the poles were set in individual holes or in continuous trenches. Walls were made by weaving saplings and cane around the poles, and the outer surface of the walls was sometimes covered with sun-baked clay or daub. Roofs were covered with thatch, with a small hole left in the middle to allow smoke to escape. Inside the houses the hearth dominated the center of the living space. Low benches used for sleeping and storage ringed the outer walls, while short partitions sometimes divided this outer space into compartments. By today's standards Mississippian houses were quite small, ranging from twelve feet to thirty feet on a side.
