A simple random sample of 10 observations was taken from a large normal population. the sample mean and the population standard deviation were determined to be 80 and 12, respectively. a 99% population mean confidence interval is approximately ____.

Answers

Answer 1
What we are looking for is the confidence interval.

Given:

Sample it is denoted by n = 10 

Mean = 80

Standard deviation = 12

Confidence Interval = 99%


Now compute for the margin of error, the formula is Za/2 * σ/√(n)


A 99% level of confidence has a critical value of zα/2 = 2.58.


The standard error is σ/√(n) = 3.162


Multiply 2.58 by 3.162 = 9.8 is the margin of error.


The formula for confidence interval is x̅ ± Za/2 * σ/√(n)

= 80 ± 9.8

= 70.2 < x< 89.8

In patrol mode,the media only cover a certain part of the story that is alligned with the agenda that they're trying to achieve

Final answer:

According to Amber Boydstun, the media tends to have a preference for breaking news and a pattern of covering stories in depth that align with audience interests or sensationalist appeal, which can result in biased coverage and influence on public opinion.

Explanation:

According to political scientist Amber Boydstun, the media has a preference for breaking stories and a pattern for covering them in greater depth. T

his can be seen in the way media outlets prioritize stories that are sensational or highly impactful on a local scale, often at the expense of detailed and in-depth coverage of broader, yet less sensational issues. The media's powerful influence, especially in political discourse and election coverage, can significantly shape public perception and voter behavior.

However, due to the pursuit of profits and the fierce competition in the media market, there is often a focus on trivialization, tabloidization, and sensationalism.

This leads to a greater emphasis on entertainment, gossip, and scandal, rather than on in-depth analysis of complicated problems. In some cases, political news broadcasts become an uncritical relaying of politicians' statements rather than a source of investigative journalism offering a wide range of policy perspectives.

Despite these tendencies, it's noteworthy that differences among media outlets do exist, with some prioritizing government and politics coverage, while others focus on softer news categories like crimes and celebrities. Nonetheless, the impact of media coverage on public opinion, and thus on democratic processes, remains profound.

A plaintiff who believes that he or she has been injured by the defendant can file a cross-complaint against the defendant true false

Answers

False the plaintiff can not file anything.

Final answer:

No, it is false that a plaintiff can file a cross-complaint against the defendant; a cross-complaint is filed by the defendant against the plaintiff or a third party, not by the plaintiff.

Explanation:

A plaintiff who believes that he or she has been injured by the defendant can file a cross-complaint against the defendant is false. A cross-complaint, also known as a counterclaim, is typically filed by the defendant against the plaintiff or against a third party, not by the plaintiff against the defendant. The plaintiff begins legal proceedings with a complaint against the defendant seeking compensatory relief for the harm suffered. In response, the defendant may file a cross-complaint alleging their own grievances against the plaintiff, or they can dispute the plaintiff's claim.

In civil litigation, the private party alleging harm or civil injury, known as the plaintiff, initiates the lawsuit by filing a complaint. The defendant, the party being accused of causing harm, responds to this complaint. If the defendant has a claim against the plaintiff, they may then file a cross-complaint as part of their defense to assert their own claims.
