Answer:
The sample size needed if the margin of error of the confidence interval is to be about 0.04 is 18.
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 .
The margin of error is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
Past studies suggest this proportion will be about 0.15
This means that
Find the sample size needed if the margin of error of the confidence interval is to be about 0.04
This is n when M = 0.04. So
Rounding up
The sample size needed if the margin of error of the confidence interval is to be about 0.04 is 18.
Answer:
Step-by-step explanation:
it will be 59,000 because i add it all up
I think its 230 because J to G is a straight 180 degree line which means the circle is cut in half which means that jfg is 180, and we can find f to g because its 180-127 which gets us 53, and since F to I and J to G are straight lines I believe that means the opposing angle J to I is also 53 meaning you can take 180-77-53 and get G to H and add that to the 180 you got from JFG and get 230
