-The bound on error of estimation, B , associated with a confidence interval is (z critical value) ·(standard error of the statistic) . ... Sample Size The sample size required to estimate a population proportion  to within an amount B with 95% confidence is The value of  may be estimated by prior information.

-P-value and margin of error are not same.

-A margin of error tells you how many percentage points your results will differ from the real population value. For example, a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time.

-The margin of error determines how reliable the survey is or how reliable the results of the experiment are. ... This is captured in statistics as margin of error. The higher the margin of error, the less likely it is that the results of the survey are true for the whole population.

-Population distribution means the pattern of where people live. World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people.

These notes are from sources found online not mine If you want the sites just comment and ill give you them!

M-(10)=-20
Zina [86]
The answer is -10. I think about negative numbers on a number line with numbers being behind and in front of the zero. To check the answer you can imagine being on -10 and when it says to minus a number you always know that it’s going to go further into the negative. So -10-10 is -20.
