Answer:
Suppose you want to assess student attitudes about the new campus center by surveying 100 students at your school. In this example, the group of 100 students represents the Sample, and all of the students at your school represent the Population.
Step-by-step explanation:
Previous concepts
The term sample represent a set of observations or individuals selected from a population. And we can have a random sample (when all the individuals have the same probability of being selected) or a non random sample (when not all the individuals have probability of inclusion into the sample)
The term population represent the total of observations or individuals with a common characteristic.
If N represent the sample of the population and n the sample size we have always this inequality:
Solution to the problem

Answer:
When 6 helicopters are produced weekly, the company's profit is <u>14 thousand dollars.</u>
Step-by-step explanation:
As per the given statement:
The company profit (in thousands of dollars), as a function of the number of helicopters produced per week can be modeled by a function.
The function that models the scenario is:
......[1]
where
f(h) represents the company's profit
h represents the number of helicopters produced per week.
It is also given that when 1 helicopter is produced per week, the company’s profit is 4 thousand dollars.
Maximum profit for company 22 thousand dollars, occurs when 4 helicopters are produced per week
⇒ and
we have to find when 6 helicopters are produced weekly, the company profit is;
⇒ h = 6 helicopters
Substitute this value in [1] to solve for f(6);
=
Therefore, the company profit is, 14 thousand dollars.
