1. A bowl contains five chips numbered 1 to 5. A sample of two drawn without replacement from this finite population is said to be random if all possible pairs of the five chips have an equal chance to be drawn. What is the expected value of the sample mean (of the numbers drawn)? What is the variance of the sample mean? Solve these by listing down all possible scenarios.
