Answer:
unlikely
Step-by-step explanation:
if it was impossible it would be 0/8
Answer:
860
Step-by-step explanation:
A non-response bias would mean that there are some non-response surveys, which will create a bias in the survey results. Because the survey didn't include information from those who are not responded.
If there will be 860 surveys back, this would prevent non-response bias
Answer: A I did the work on my notebook by the way.
Answer:
1,080
Why:
First. you have to turn the feet into inches which would make the room 120in. by 144in. and the area of the room would be 17,280 square inches.
Then you have to find the area of the square tiles, and since the sides of the square are the same length , 4x4=16
Last, you have to divide 17,280 by 16 which would give you 1080 tiles
Using sampling concepts, it is found that the correct option is:
This is a convenience sample and likely overestimates support for raising funds.
<h3>How are samples classified?</h3>
Samples may be classified as:
- Convenient: Drawn from a conveniently available pool.
- Random: All the options into a hat and drawn some of them.
- Systematic: Every kth element is taken.
- Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
- Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
In this problem, people at the pool were surveyed, hence it is a convenience sampling.
Also, since it only involved pool users, the proportion may be overestimated, hence the correct option is:
This is a convenience sample and likely overestimates support for raising funds.
