Answer:
C. Different sample proportions would result each time, but for either sample size, they would be centered (have their mean) at the true population proportion.
Step-by-step explanation:
From the given information;
A political polling agency wants to take a random sample of registered voters and ask whether or not they will vote for a certain candidate.
A random sample is usually an outcome of any experiment that cannot be predicted before the result.
SO;
One plan is to select 400 voters, another plan is to select 1,600 voters
If the study were conducted repeatedly (selecting different samples of people each time);
Different sample proportions would result each time, but for either sample size, they would be centered (have their mean) at the true population proportion. This is because a sample proportion deals with random experiments that cannot be predicted in advance and they are quite known to be centered about the population proportion.
You can find 84 two different ways by dividing by 2,3,4.
84÷2=42
84÷3=28
84÷4=21
Answer:
the original amount is $1,642
Step-by-step explanation:
The computation of the original amount is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
So,
Present value = Future value ÷ (1 + rate of interest)^number of years
= $3,024.56 ÷ (1 + 0.26 ÷ 2)^5
= $1,642
Hence, the original amount is $1,642
