A confidence interval for the true mean SAT score of the graduating high school seniors will be (496; 536)
<h3>What is a confidence interval?</h3>
A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics.
Mean score ± margin of error
Margin of Error = 20
Mean SAT score = 516
Hence,the confidence interval will be:-
= 516 ± 20
Lower boundary = 516 - 20 = 496
Upper boundary = 516 + 20 = 536

Answer:
Hello! I hope I am correct! :)
Step-by-step explanation:
Let’s first calculate the black circle & the white space.
Since there is more white space than the black circle, we already know that the white space will have more probability.
These are the steps you need to do, in order to so love this problem:
1. Find the area of both, the white space and the black circle.
2. Divide both of them by the area of the square.
3. Do all these steps to find the probability/hitting.
Part A:
Black circle: ( π *1^2) / ( π 5^2) = 1/25 = .04 or 3.14% chance.
So we can tell it’s close to zero.
Part B: 1 - .04 = 0.96 or 97%
This is close to one.
(Remember I am not saying the exact, it’s a estimate)

ANSWER
EXPLANATION
We want to find an odds ratio from a given probability, which is
We subtract the numerator 1 from the denominator 4 to obtain
The answer is the number of unfavorable outcomes.
The Odds can then be expressed as
The ratio of favourable outcomes to unfavorable outcomes.
Or
A right triangle has one angle that's 90° and a corner that looks like an L. Obtuse triangles have one angle that's greater than 90°. In acute triangles, all the angles are less than 90°.
