Question

A simple random sample of size n from a finite population of size N is a sample selected such that each possible sample of size a. N has the same probability of being selected b. n has a probability of 0.5 of being selected c. n has a probability of 0.1 of being selected d. n has the same probability of being selected The number of random samples (without replacement) of size 3 that can be drawn from a population of size 1s a. 15 b. 10 C. 20 d. 125 There are 6 children in a family. The number of children defines a population. The number of simple random samples of size 2 (without replacement) which are possible equals a. 12 b. 15 c. 3 d. 16
