Answer:
3 1/2 cups butter
Step-by-step explanation:
Multiply the batches (5) by the amount of butter (3/4 cup)
5/1 * 3/4 = 5*3 = 15; 1*4 =4 15/4

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
