Answer:
n=14
Step-by-step explanation:
multiply both sides by two to get rid of 1/2 and you find n=14
A= 3,2
B= -1,-1
C= 3,4
D= 1,4
You must multiply each number for example 8*4*2= 64 so the after math is 64 after all the work the answer is ^4.
Answer:
The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).
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:

95% 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 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).
