Answer:
a) sample of size n from the population has an equal chance of being selected.
b) Every member of the population has an equal chance of being included in the sample.
Step-by-step explanation:
Simple random sampling:
- It is a type of probabilistic sampling.
- It is an unbiased representation of population.
- The probability of selection is equal for every observation.
- A sample is taken in such a way that each member has an equal probability of being selected.
- A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
- Thus,the correct interpretation is given by,
a) sample of size n from the population has an equal chance of being selected.
b) Every member of the population has an equal chance of being included in the sample.
- c) The simplest method of selection is used to create a representative sample.
The statement is false.
There is no pattern or technique used for selection. The selection is purely random.
- d) Each subset of the population has an equal chance of being included in the sample.
The statement is false.
Each object of the population has an equal chance of being included in the sample. and not each subset.
- e) Every sample of size n from the population has a proportionally weighted chance of being selected.
The given statement is false.
I also think it is c. Just look over and make sure or your positive that i am right
8? Is it, I am not good at math
Answer:
I can try ^^
Step-by-step explanation:
D.
Hey there!
To find the opposite of a number, you switch its sign, and to do so, you would multiply by -1. This gives us the equation below.
n=-n+96
To find our number, we need to isolate all of our n's on one side of the equation. Let's try adding n to both sides.
2n=96
We divide both sides by 2.
n=48
As you can see, the opposite of 48 is -48, and 48 is 96 more than -48.
Therefore, our number is 48.
I hope this helps!
