Answer:
6.8 if it is rounding to the tenth. 6.9 if its rounding to the hundredth.
Answer:
The 99.9% confidence interval for the population proportion is (0.548, 0.896).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
99.9% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99.9% confidence interval for the population proportion is (0.548, 0.896).
While I'm not too sure what you mean the real number system, I can help you simplify this equation. Through the process of factoring, this equation simplifys down to:
x^10(x^6−2x^5−x^4+4x^3−x^2−2x+1)
Answer:
38.21 in
Step-by-step explanation:
Given data
C= 120meters
We also know that circumference
C=2πr
Substitute
120=2*3.142*r
120= 6.28r
r= 120/6.28
r= 19.10 m
Hence the diamter D
D= r*2
D= 38.21 in
