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.
A. With too many elders, the population would be without necessary amount of labor to supply the needs. Encouraging women to work and raise children, the government would obviously have more wealth because women would be working and they would also have a plan for the future, which are the children, that in whitin a while would have the appropriate age to work and be in the market.
Answer:
4/25
Explanation:
Idk, if the negative sign on the top has anything to do with rewriting it as a simplified fraction, but 4/25 would be the most simplified it can get.
Your rpm will go up the answer is B
