The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less is 0.0020
<h3>What is probability? </h3>
Probability can be defined as the likelihood of an event to occur. In statistics, the mean of the sample distribution typically shows the probability of the population.
From the parameters given:
- The sample size (n) = 55 patients
- Let's assume that the mean (x) = 32 (i.e. 58.2%) of the patients
The sample proportion
can be computed by using the expression:



If the percentage of the probability of all patients in the emergency room = 0.75
The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less can be computed as:



From the Z distribution table:

Answer to Question 1:
The behaviour of the students who hastily write what they consider a "C" level essay after being repeatedly told they can't make an "A" or "B" is a consequence of Reinforcement.
The answer, therefore, is D.
Explanation:
Reinforcement in behavioural psychology refers to the process of encouraging or entrenching a belief system or pattern of behaviour. It can also be defined as any stimuli which stimulate a thought pattern and engrains the probability of a specific response to a particular stimulus. Reinforcements are usually more effective when it comes from a person of perceived to be in a position of authority.
The high school students were verbally programmed by the instructor, who has the authority to mark their scripts, into thinking they will never be able to make an "A" or a "B". The result is that the students didn't even try to put in efforts that would have led to an A or a B because even if they did, the instructor has the power to ensure that no one score an "A" or a "B".
The challenge here is not that the students couldn't write "A" grade essays. In their mind, there was no point trying given that the ability lay with the instructor to ensure that what he said will happen. In any case, the instructors intended behavioural response was achieved.
2. The correct answer to the question of Acquisition and Extinction as indicated on the graph is B.
The strength of the response increases then decreases over time.
Acquisition happens when a neutral stimulus turns into a conditioned stimulus.
When a behavior begins to diminish or even disappear completely as a result of the gradual removal of a conditioned response, extinction is said to have occurred.

Answer:
c. prevented supplies from entering or leaving.
Explanation:
The siege of Vicksburg was a military campaign that took place during the American Civil War. In this campaign, the Union Army was able to prevent supplies from entering or leaving Vicksburg. This was the last major Confederate stronghold on the Mississippi River, and by capturing it, General Ulysses S. Grant was able to fulfill what was known as the Anaconda Plan.
