4.2³ = 74.088. If the 4.2 is accurate, this is actually not an estimate but an exact answer. You can of course round it to 74, then it becomes an estimate.
Answer:
X= 5/12 + 1/24y
Y= -10 + 29x
Step-by-step explanation:
2(10- 24x)+ 2y 2(10- 24x)+ 2y
20 - 48x +2y 20 - 48x +2y
48x =20 +2y -2y = 20- 48x
/48 /48 /48 /-2 /-2 /-2
x= 5/12 + 1/24y y= -10 +29x

Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
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 z-score that has a p-value of .
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
