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: 3,240,000 L
Explanation:
Each tree requires 20 L of water per day for 180 days.
Each tree therefore requires;
= 20 * 180
= 3,600 L per day
There are 900 trees to be grown;
= 900 * 3,600
= 3,240,000 L of water are required for 900 trees.

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.
Answer:
The answer is below
Explanation:
The theory of color vision best that best explains this deficiency is called TRICHROMATIC COLOR THEORY. It was originally proposed by Thomas Young and later refined by Hermann von Helmholtz.
Here, Yasser’s color-blindness is associated with deficiencies in various cones. The most probable are red and green cones because of their high chance in men than women.
The theory of color vision best explains why he might see an afterimage is known as OPPONENT - PROCESS THEORY. It was originally proposed by Ewald Hering.
This is based on the principle that supposing Yasser, stared at a red image for a while and then stared at a blank white page, he would likely see an imprint of the image, but in green.
