Answer:
Our population of interest represent all the adults in United states who never travel using commercial airlines.
The sample on this case represent the people surveyed in United States who never travel using commercial airlines.
For this case the value obtained represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by
Step-by-step explanation:
A statistic is a "characteristic of a sample". And the statistic allows "estimate the value of a population parameter".
A parameter is a value who represent the population of interest.
For this case we have a sample size of size n = 2276
The proportion estimated of people that nevel travel using commercial airlines was:
or 33%

Answer:
(i)
y-intercept is -2
(ii)
slope is
(iii)
slope is positive
(iv)
another point is (3,0)
Step-by-step explanation:
We are given equation as
now, we can compare it with slope intercept form of line
y=mx+b
where
m is slope
b is y-intercept
we get
So,
(i)
y-intercept is -2
(ii)
slope is
(iii)
we can see that
is a fraction and positive
so, slope is positive
(iv)
we can select any random value of x and find y
that will give us second point
Let's assume
x=3
So, another point is (3,0)
(v)
