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:
All of them would be under $65
I believe it would be d. equilateral. becuz a equilateral triangle is a triangle with 3 equal sides, and 3 equal angles.
An outlier number is the number that's completely different from the rest.
For example;
1, 15, 17, 16, 14.
"1" is the outlier.
Our list of numbers range (on average) from 7-12.
Let's look at our answer choices.
A.) There is one outlier that indicates an unusually large number of players on that team.
This is true, as we have 21, the one and only outlier in our list.
Your answer is A.)
I hope this helps!
