You wish to use a long string of random digits to randomly assign one-half of a group of 1000 students to a treatment group. You assign consecutive
number labels to all the students, starting with zero. Your then break the long
string into chunks of digits. Should the chunks consist of single digits, pairs,
triplets, or quadruplets?

Iwould think that the correct answer is 8.1

1. 5/82.95% is better than 7/8

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
