He swerved across the interstate as a large truck sped towards him at what seemed to be the speed of light. His husband screamed,
“Watch out!” A flash of red, an ear splitting noise of metal against metal, a crack of bone, and then silence. He felt immediate peace but at the same time felt nothing. He saw only a bright light, but nothing. It was a feeling of existing in nonexistence. The only way the man would be able to describe his death when he awoke was floating in pain, peace, darkness, and light all at once. When suddenly, he felt a shock course through his veins.
“Damian!” His eyes flashed open, and reality came crashing into him like the truck had crashed into his body. Doctors stood around him, smiling with relief.
“What?” He sputtered, it was all he could manage.
“Welcome back, Damian,” said one of the doctors. His head was full of cotton, his heart was being squeezed, his arm was cut in half. He looked to the side and saw that his arm was in fact cut in half. He shivered.
“Gary?” He asked, almost not wanting to know.
“I’m so sorry, Damian,” a doctor answered sorrowfully. “He’s gone.”
The only way he would describe his grief when he awoke was floating in pain, peace, darkness, and light all at once.

9.A game show producer asked 100 randomly selected adults, “Have you ever bungee jumped?” Of the adults surveyed, 14 said “Yes!” Is there convincing statistical evidence that the true proportion of all adults that have bungee jumped is more than 10%?
(A)No, because the difference between the sample proportion and the population proportion is only 0.04, which is not greater than 0.05.
(B)No, because the probability of observing a sample proportion at least as large as 0.14, if the population proportion is 0.10, is greater than 0.05.
(C)Yes, because the probability of observing a sample proportion at least as large as 0.14, if the population proportion is 0.10, is greater than 0.05.
(D)Yes, because the probability of observing a sample proportion at least as large as 0.14, if the population proportion is 0.10, is less than 0.05.
(E)Yes, because the difference between the sample proportion and the population proportion is 0.04, which is less than 0.05.
Answers
Answer: B.
Explanation: No, Because the probability of observing a sample proportion at least as large as 0.14, if the population proportion is 0.10, is greater than 0.05.
Let us recall from given question that,
H0:p=0.80
Ha:p≠0.80 (which is the two tailed test)
For the p-value we have,
P-value: Let us assume that the null hypothesis is true, then the probability of observing the sample statistics or the more extreme,
Therefore if p= 0.80, the probability of observing or detecting proportion of samples is of at least 0.84 or at most 0.76 is 0.273.
What occurs in Type I error?A Type I error occurs in hypothesis testing when one is rejects the null hypothesis and the null hypothesis is true.
To reject the null hypothesis, statisticians conduct hypothesis testing. However, the process is always accompanied by the possibility of making a mistake. These are referred to as hypothesis testing errors.
Type I and Type II errors are the two mutually exclusive errors in hypothesis testing. Type II errors occur when a statistician fails to reject a false null hypothesis, whereas Type I errors occur when a statistician correctly rejects a genuine null hypothesis. So, c is the right response.
Therefore if p= 0.80, the probability of observing or detecting proportion of samples is of at least 0.84 or at most 0.76 is 0.273.

Tara mows lawns as a summer job. She
charges $9.50 for each lawn plus $2.50 for
every hour she works. The gasoline she needs
to mow an average lawn costs $1.85. Write an
expression for the profit Tara makes from
cutting a single lawn.
Answers
Answer:
9.50+(2.50x)1.85
Explanation:
I think this might be it because you don't really get the time she works for a lawn
Answer:
7.65 + 2.50h
Explanation:
The original expression for finding her profit is:
($9.50x + $2.50h) - 1.85x
x being the number of lawns she mows
h being the number of hours she works
If she were to only mow one lawn, the expression would be:
($9.50(1) + $2.50h) - 1.85(1)
h remains constant because we do not know the number of hours she works for
The above expression simplified:
($9.50 + $2.50h) - 1.85
So, I do... $9.50 - 1.85 to get...
$7.65 +$2.50h

You survey a random sample of 50 households and want to compute the probability that at least one of the households does not purchase toilet paper. Which of the following is appropriate for modeling this distribution?
(A)Binomial distribution
(B)Geometric distribution
(C)Normal distribution
(D)t distribution
(E)Chi-square distribution
Answers
Answer:
A) Binomial Distribution
Explanation:
This situation is binary because there are two options. Either success (buy toilet paper) or failure (do not buy toilet paper). The trials are independent, there are a fixed number of trials, and the probability of success remains the same for each trial. Therefore, it is a binomial distribution.

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
Answers
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.

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.
