A population consists of N = 4 numbers: 12, 15, 20, 24 with a mean of μ = 17.75. A random sample of n = 2 is selected. How many possible random samples are there when sampling without replacement? samples List the possible samples. (Enter your answers as a comma-separated list. Enter your answers in set notation. Enter each answer only once.) Find the sampling distribution for the sample mean x and display it as a table. (Enter your values of x in increasing order from top to bottom. Enter your probabilities as fractions.) P(x) x
