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

A true positive is when a person who is infected receives a positive test (someone whose test comes back positive but who doesn't really have the infection would be called a false positive).

D/(I + U + D + N)
C < or = to $45
