    simple Sampling with and without replacement

    A population consists of the monthly salaries of the 3 employees at an office. The monthly salaries are: Employee {1K , 2K , 4K }
    1. Give all possible samples of size 2 sampling with and without replacement. How many possible samples are there with and without replacement?
    2. Compute the sampling distribution of the sample mean of a sample of size 2.
    3. Compute the sampling distribution of the sample median of a sample of size 2.
    4. Find the mean and standard deviation of both sampling distributions in 2. and 3

    I'd appreciate any help with this, thanks.
