Answer:
a. .92
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 of the interval is:
The lower bound is the point estimate subtracted by the margin of error.
The upper bound is the point estimate added to the margin of error.
Point estimate:
The confidence interval is symmetric, so it is the mean between the two bounds.
In this problem:
Sample of 400, which means that 
Margin of error is the estimate subtracted by the lower bound. So 
We have to find z.
has a pvalue of 0.96.
This means that:
Confidence level:
So the correct answer is:
a. .92
Answer:
B. 3
Step-by-step explanation:
16 : 4 = 12 : |GD|
4=12 : |GD|
|GD| = 12 : 4 = 3, Answer is B
Plug 4 for x
f(4) = 6(4) - 2
f(4) = 24 - 2
Solution: f(4) = 22
