1)
An experiment with three outcomes has been repeated 50 times, and it was learned that E1occurred 20 times, E2occurred 11 times, and E3occurred 19 times. Assign probabilities to the following outcomes for E1, E2and E3. Round your answer to two decimal places.
P(E1) | |
P(E2) | |
P(E3) |
2)Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 100 bank accounts, we want to take a random sample of nine accounts in order to learn about the population. How many different random samples of nine accounts are possible?
