Answer:
The correct answer is
(0.0128, 0.0532)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, 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:
In a random sample of 300 circuits, 10 are defective. This means that
and 
Calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool.
So
= 0.05, 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 correct answer is
(0.0128, 0.0532)
Answer:
y=3x^2 -15x-42
Step-by-step explanation:
Answer:
the length is 10
Step-by-step explanation:
√(1 - 9)2 + (12 - 18)2 =
√(-8)2 + (-6)2 = √64 + 36 =
√100= 10
Answer:
We have z - 8 = 4 or z - 8 = -4;
Then, z = 12 or z = 4;
The correct answer is d).
