Answer:
The 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).
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:

90% 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 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).
Answer: 15
Step-step-explanation:
Polynomial division yields

As

, you have the remainder term approaching

, so the horizontal asymptote is the line

.
Answer:
Option: A is correct.
A) a part of a line that has one endpoint and extends indefinitely in one direction
Step-by-step explanation:
" A ray is a line that starts at a given point and goes off for ever in some direction. It may pass through another point as it does so "
Hence, option A is correct.
( The definition of Ray is:
A) a part of a line that has one endpoint and extends indefinitely in one direction )
Yes, your answer is correct.
