Random selection (D) you most take a small portion of the large population and analyze that and guess for the rest, an educational guess.
Answer:Accordingly, the Necessary Sample Size is calculated as follows:
Necessary Sample Size = (Z-score)² * StdDev*(1-StdDev) / (margin of error)²
For example, given a 95% confidence level, 0.5 standard deviation, and a margin of error (confidence interval) of +/- 5%. Necessary Sample Size =
((1.96)² x 0.5(0.5)) / (0.05)²
(3.8416 x 0.25) / .0025
0.9604 / 0.0025
384.16
So in order to get 95% confidence level, with confidence interval of +/- 5%, and standard deviation of 0.5, I have to survey 385 samples.
As I usually calculate the average value on 100 samples. So what is the confidence level I can get?
Is anyone who has experience on this can share something.
Answer:
cognition, its prototypes and concepts
Explanation:
Cognition in a term used in describing the process of thinking, understanding and expression of knowledge.
Prototypes which are the first or original experiment on which other subsequent actions are based upon function within cognition through face thinking or expression.
The difference between convergent thinking and divergent thinking is in the fact that convergent thinking has to do with a cognitive method of reasoning where an action is brought to a focus or put together within a context while divergent thinking encourages the contrary.

Answer: B. He is interested in designing machines that help people with disabilities
Explanation:
The options include:
A. He doesn’t enjoy solving problems by working as a team and using analytical skills.
B He is interested in designing machines that help people with disabilities.
C He enjoys writing, and he’s really good at it.
D He wants to get to know lots of different kinds of people around the world.
Biomedical engineers are the people who helps in the development of new devices and new equipment which will be used to improve the health of people.
In this case, since Mark chooses to pursue biomedical engineering, his reason will be because he's interested in designing machines that help people with disabilities.
