Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of the population proportion.
Here we can see that the sample size is inversely proportion withe square of margin of error.
i.e. 
By the equation inverse variation, we have
Given : 
Then, we have
Hence, the sample size will now have to be 4000.
Answer:
Step-by-step explanation:
In the given division, when 24.725 is divided by 215,
Step 1 is the wrong step.
Quotient in first step will be 0.1 .
Part C.
215) 24.725 (0.115
<u> 215</u>
322
<u>215</u>
1075
<u>1075</u>
0
Therefore, the correct way to divide should be as agove.
Quotient after division should be 0.115.
