The second equation gives
, but
for any real
, so we can ignore this equation.
This leaves us with
where
is any integer.

Answer:
d.
Step-by-step explanation:
Inferential Statistics is one of two statistical methods that is used to analyze data by drawing conclusion about a bigger population from a sample. In other words, inferential statistics allows a researcher to make assumptions and arrive at conclusions about a larger group known as the population, by using just a small portion known as the sample of the population as a study. The study of this small portion is then used to explain the behaviour of the entire population. Random sampling is carried out to ensure that the sample is a true representation of the population
It involves:
- A definition of the population to be studied.
- Drawing a sample out of this population.
- Analysis of data.
You do 14 divided by 16 which is 0.875 times by 100
which is 87.5 so that means 14/16 in a percentage is 87.5 %
We have that
set of data [<span>8, 12, 15, 17, 18]
step 1
Find the mean
</span>[8+ 12 + 15 + 17 + 18]/5-------> 70/5------> 14
step 2
for each number: subtract the Mean and square the result
(8-14)²----->36
(12-14)²----> 4
(15-14)²----> 1
(17-14)²----> 9
(18-14)²----> 16
step 3
<span> work out the mean of those squared differences
[36+4+1+9+16]/5-----> 66/5-----> 13.2----> </span><span>this value is called the "Variance"
step 4
</span><span>Take the square root of that
</span>standard desviation=√13.2-----> 3.63-------> 4
the answer is
4
