Transcribed Image Text: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.
