Answer:
68
Step-by-step explanation:
m7 + m8 = Straight line = 180
So, m7 = 180 - 112 = 68
19 27 28 29 30 315 64 29 46 is the
\
Since the radius is 12, the equation is
.. x^2 +y^2 = 144
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.
5.4 because the 9 bumps it to 5.35.
And the 5 bumps it to 5.4.
