The eyes and the brain are important in helping people see. Light passes through the eyes and this light gets transformed into electrical signals which are sent to the brain that helps make sense of the object that is seen.

<h3 /><h3>How People See</h3>

Light is incident on an object (or strikes an object). Some of it get absorbed, some are reflected into a human's eye.
Light that bounces off the object is transmitted across the cornea, the transparent outer layer of the eye. It refracts the light and makes things look sharp and clear.
Then the light enters the pupil which is the opening in the eye controlled by the iris or the colored part of the eye. The iris changes the size of the pupil and controls the amount of light that enters the eye. When there is bright light, the pupil becomes smaller. In dim light, the opposite happens and the pupil becomes bigger.
At the back of the pupil is the lens which again helps focus the light. Its shape changes depending on the distances of the objects that is being looked at.
The light rays are focused by the lens so that they all converge in the retina which is at the back of the eye. The retina has many specialized cells which are sensitive to light. These cells transform light energy into electrical signals or nerve impulses which form a rough inverted image of the object the person is looking at.
The electrical signals travel to the brain through the optic nerve. The brain turns the image upright and adds more detail to the vision.

If the wait time is less than 30 minutes for 75% of all patients in the emergency room, what is the probability that the

Greeley [361]

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 $\mathbf{\hat p}$ can be computed by using the expression:

$\mathbf{\hat p = \dfrac{x}{n}}$

$\mathbf{\hat p = \dfrac{32}{55}}$

$\mathbf{\hat p =0.582}$

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:

$\mathbf{( \hat P \leq 0.582) = P \Big( \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}} \leq \dfrac{0.582 - 0.75}{\sqrt{\dfrac{0.75(1-0.75)}{55}}} \Big )}$

$\mathbf{( \hat P \leq 0.582 )= P \Big( Z \leq \dfrac{-0.168}{\sqrt{0.003409}} \Big )}$

$\mathbf{( \hat P \leq 0.582) = P \Big( Z \leq -2.88 \Big )}$

From the Z distribution table:

$\mathbf{( \hat P \leq 0.582) = 0.00198}$

$\mathbf{( \hat P \leq 0.582) \simeq 0.0020}$

<h3>What is Logical transition?</h3>

The term Transitions are known to be a kind of words that set out a form of logical linkage between sentences and also between paragraphs, or between full parts of an essay.

Note that transitions can be seen as a whole sentences, phrases, or single words and it is often use to depict logical relationships.
