The sample function is used to generate a random sample from a given population. It can be used to sample with or without replacement by using the replace argument (the default is F). The only obligatory argument is a vector of data which will constitute the population from which the sample will be drawn. whether the sampling is with or without replacement, the expected value of the sample mean is the average of the numbers on all the tickets in the box, for random sampling with or without replacement. Consider a 0-1 box of tickets. The population percentage is the fraction of tickets labeled "1." Equivalently, it is the mean of the list of the ...

- Sampling with replacement versus sampling without replacement What are the main types of sampling and how is each done? Simple Random Sampling : A simple random sample (SRS) of size n is produced by a scheme which ensures that each subgroup of the population of size n has an equal probability of being chosen as the sample. |
- Two successive drawn of 3 balls are made: TOTAL = 12: 5W, 7B 1st draw(a) with replacement Draw 3 P(3-W) = (5/12)(5/12)(5/12) = 125/1728 | 2nd draw(b)without replacement. Draw 3 P(3-B) = (7/12)(6/11)(5/10) = 210/1320 = 21/132 P(both happening) = (125/1728)(21/132) |
