An organization that strives to hold agencies accountable for truth in news reporting plans to select a random sample of 100 news stories from major U.S. news agencies in order to estimate the proportion of news stories produced by major U.S. news agencies that contain false information. A 90 percent confidence interval for the proportion of all news stories that contain false information will then be constructed. Before selecting the sample, the organization determines that they want to make the margin of error as small as possible. Which of the following is the best way for them to decrease the margin of error?
(A)Increase the confidence level to 95%.
(B)Increase the confidence level to 99%.
(C) Include a wider diversity of sources, such as local and international news agencies.
(D)Include news stories over a broad period of time, such as over the past decade.

8. Candidate A and Candidate B are running for president. You are planning a survey to determine what proportion of registered voters plan to vote for Candidate A (p). You will contact a random sample of registered voters. You want to estimate p with 99% confidence and a margin of error no greater than 0.01. What is the minimum number of registered voters you will need to survey in order to meet these requirements?
(A)97
(B)166
(C)6,766
(D)9,604
(E)16,590
Answer:
The correct answer is (E).
The minimum sample size of registered voters that are needs to be surveyed in order to meet these requirements is 16590 registered voters.
What is the required sample size?The sample size, n, can be calculated using the formula below:
[tex]n = \frac{z^{2}×p(1-p)}{(\frac{ε}{2}) ^{2}}[/tex]
where:
z = is the z scoreε is the margin of errorpis the population proportionFor the data provided:
z for 99% confidence = 2.58
ε/2 = 0.005
p = 0.5
Substituting the values:
[tex]n = \frac{2.58^{2}×0.5(1-0.5)}{0.005^{2}} = 16641[/tex]
Therefore, the minimum sample size of registered voters that are needs to be surveyed in order to meet these requirements is 16590 registered voters.

What is technology?Technology refers to the tools, techniques, and processes that are used to create, develop, and improve products, services, and processes.
It encompasses a wide range of fields such as electronics, telecommunications, software, computers, and robotics.
College campuses typically offer free Wi-Fi for their students, which can be used to access the internet and other resources on a laptop, tablet, or smartphone.
Using these resources can help cut down on technology expenses, as students can use their own devices instead of purchasing new ones or relying on friends to borrow theirs.
Additionally, using a smartphone for communication needs may not be as efficient or practical as using a laptop or tablet, and using a typewriter is an outdated technology that is not commonly used anymore.
Thus, the correct option is C.

Explanation:
James was the lead in the school play. It was opening night. Mr. Ramirez, the director, asked James if he was ready to go on and reminded him about a few last-minute changes in the script. A number of thoughts and feelings came over James as the curtain went up. James became anxious when he saw all the faces of the audience members. Then he saw his mother, who is a professional actress, sitting in the front row. James could not relax. At that instant, he saw his psychology teacher in the audience. He knew that he needed to use the concepts learned in her class to make sense of these thoughts, feelings, and surroundings.
Describe how each of the following concepts might help James give a strong performance.
State-dependent memory
Arousal theory
Positive reinforcement
Selective attention
Imagery
Social facilitation
Sensory adaptation
Answer:
Check below for the answer and explanations
Explanation:
State-dependent memory: is the process of remembering things because they happen when you were in a state that is similar to your current state. Before the opening night, James would have gone through series of rehearsals, it will be easy for him to recollect the things he said or did during the rehearsal and apply same in the opening night.
Arousal theory: This theory explains that people tend to have a better performance when they are psychologically motivated. James felt motivated when he saw his psychology teacher in the audience. This motivation will enhance is performance.
Positive reinforcement: James motivated himself by wanting to use the concept learnt in his psychology class to have a positive thought about the surrounding atmosphere. This is a positive reinforcement because James felt motivated after this consideration.
Selective attention: This is the process of focusing only on relevant information or object. James paid more attention to those whose presence can aid his performance. He did not have to set his gaze on every member of the audience.
Imagery: In this context, imagery is the use of mental, imaginary pictures to influence one's thought process. As James is on the stage, there should be a mental picture of when he was taking similar roles during the rehearsals, this will help him perform better.
Social facilitation: The presence of a large audience aids the performance of some people. They tend to perform better in the presence of crowd. James can utilize the advantage of the cheers and the applause he receives from the audience for a better performance.
Sensory adaptation: As James spends more time outside performing, his senses tend to adapt to that atmosphere and the initial fright and timidity will disappear. At this stage, he begins to perform incredibly well.
State dependence memory is the process of remembering things due to what happened. They take place when you are in a state similar to the current state.
Arousal theory suggests that people are driven to take actions that tend to maintain an optimal level of psychological arousal. Selective attention is a process that allows the individual to focus on a specific topic, or input for further processing. Imagery is any visual figurative language that evokes a mental image. Social facilitation is the improvement or the decrease of performance when working together with other people. Sensory adaptation is the reduction of the sensitivity to stimus after long exposure.Learn more about the lead in the school play. It was opening night.
