<h2>D. This is an experiment with blocking </h2><h2 />
For your question: "A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half
of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To
determine who listens and who does not, the teacher identifies the two students who scored highest on the last test
and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-
scoring students and continues in this manner until each student has their instructions. Which of the following best
describes this plan?"
The answer is D
I'm not sure what you mean, but I think the answer is 3/6
Answer:
Step-by-step explanation:
The probability that a person answered incorrectly is 4/5
P(1st answered incorrectly AND 2nd answered incorrectly AND
3rd answered incorrectly AND 4th answered incorrectly AND
5th answered incorrectly AND 6th answered incorrectly AND
7th answered incorrectly AND 8th answered incorrectly)
Since "AND" mean to multiply, the probability that none of the 8 guessed correctly is
4/5×4/5×4/5×4/5×4/5×4/5×4/5×4/5
=(4/5)^8
=0.16777216
