I would say that one of the most important Greek achievements or accomplishments since ancient Greece is its politics - to be more precise, democracy. As you may already know, ancient Greece is where democracy came to be. If it weren't for it, today we wouldn't have the idea of democracy or try to implement it into our own countries.
Answer:
Margin of Error decreases
Pvalue decreases
Power increases
Step-by-step explanation:
The margin of error decreases as sample size increases given the same level of confidence, hence, the interval gets narrower.
The margin of error = (Zcritical * σ/√n) ; where, n is the denominator, as the denomination increases, the obtained value will decrease, hence, the margin of error.
When we have a false H0, then we expect a statistical result which will reject H0, with all facts remaining unchanged , increase in sample size n, will lead to decrease in Pvalue, because a lower P value increases the significance of statistical test needed to reject H0.
The power of a fixed level test when the null hypothesis is true, higher power is required to reject the null , increasing n will increase the probability of rejecting H0, by increasing the power of a fixed level test.
-13 ÷ -21 = 13÷21 = 0.619
