Probability of A Random Sample of 955 students
I am trying to determine the probability of this scenario:
There is a population size of 955 people. Each one is assigned a random number, 1-955. I am looking at a sample of 26 people from this 955 sample, who have been assigned numbers randomly. I want to know what are the odds of a few things:
1. That all 26 people receive a number lower, meaning closer to 955, then 500
2. That 40% and then 50% of the 26 people receive a number lower, meaning closer to 955, then 500
3. That two people out of this 26 people get consecutive numbers, example: 730 and 731.
Re: Probability of A Random Sample of 955 students
When you are sampling can you pick the same person twice?
For 3. If you pick numbers 730, 731, 654, 655 in your sample does that count? Your question indicates it has to be one pair but maybe thats not what you meant.
