Answer:
The random variables which has a distribution that can be approximated by a binomial distribution is:
c. The number of students in the sample who scored above average on the SAT.
Step-by-step explanation:
The binomial distribution in this scenario will be between the number of students in the sample who scored below average on the SAT and the number of students who scored above average. Variables that have a binomial distribution must meet these four conditions:
1: The observed number of students who sat for the SAT 'n' is not variable.
2: Each student's score (observation) is purely independent of each other, either above or below average scores.
3: Each student's score (observation) shows one of the two outcomes ("success" or "failure"). Those below average are "failures." Those above average are "successes."
4: The outcome probability of "success" 'p' for each student is the same.

Answer:
A. The Fabric
Step-by-step explanation:
By definition and experimental unit is the entity which is subjected to different types of treatments during the experiment.
Here the fabric has been stained with different types of stains and and then have been treated with baking soda and bleach under different temperature environments. In the experiment each time the fabric has been given different treatment than the previous one. That's why the fabric is experimental unit in the experiment mentioned in the question.
