Answer:
Filter
Explanation:
The filter allows to select special criteria from a database in order to generate a new database in which the elements met the selected criteria.
Calculate the sample proportion (198 yes responses out of 316).

We want to test against a sample size of n = 2200 daily passengers.
In order to use the normal distribution, we should satisfy

2200*0.6266 = 1378.5
2200*(1-0.6266) = 821.5
We may use the normal distribution.
Let us use a 95% confidence interval.
The estimate for the population proportion is

where z* = 1.96 at the 95% confidence level.

Therefore
p = 0.6266 +/-0.0202 = (0.6064, 0.6468)
Answer:
At the 95% confidence level, about 60% to 64% of regular passengers will buy snacks on the train.
The firm's degree of operating leverage is 1.23. Operating leverage is the measure of the degree to which a firm or project incurs a combination of fixed and variable costs. Businesses have more leverage when they have more sales resulting in a high gross merger and less fixed and variable costs.
To solve: Change in EBIT percent / change in sales percent
Answer: Abandonment.
Explanation:
According to the Oxford's Learner's Dictionary; abandonment is defined as "<em>the act of leaving a person, thing or place with no intention of returning" </em>or "<em>the act of giving up an idea or stopping an activity with no intention of returning to it"</em>
In medicine the term changes slightly and occurs when the benefits of the protection or support that a patient recieved is taken away without proper notification after the patient has been accepted.
This can occur in a number of different ways;
- Doctor does not visit patient while the patient is at the hospital.
- Doctor refuses to treat a patient who was previously accepted without reason or motive.
- Failure to follow up with patient´s medical reports or health.
- Failure to assign a substitute when not available. (for example, a woman is giving birth and the doctor leaves the hospital without checking the patient or following up with their health status and doesn't deliver the patient's notes to the doctor who is working the other shift)
It is not considered abandonment when the doctor-patient relationship is legally terminated. This happens when the physician and the patient mutually agree to terminate the relationship.
