Answer:
a. n=4148
b. n=3909
c. The sample size is smaller if a known proportion from prior study is used. The difference in sample sizes is 239
Step-by-step explanation:
a. For sample where no preliminary estimate is given, the minimum sample size is calculated using the formula:
Where:
- Margin of error
- is the assumed proportion
#Let p=0.5, substitute in the formula to solve for n:
Hence, the minimum sample size is 4148
b. If given a preliminary estimate p=0.38, we use the same formula but substitute p with the given value:
Hence, the minimum sample size is 3909
c. Comparing the sample sizes from a and b:
Hence, the actual sample size is smaller for a known proportion from prior a prior study.
The quotient of 3,419 and 11 is 310.81.
<h3>How to illustrate the information?</h3>
It should be noted that from the information given, we are to find the quotient of 3,419 and 11 determined using an area model.
It should be noted that this simply means the division of the values given. This will be:
= 3419/11
= 310.81
Therefore, the quotient of 3,419 and 11 is 310.81.
