(Solution Download) The probability distribution shown here describes a population of measurements


The probability distribution shown here describes a population of measurements that can assume values of 0, 2, 4, and 6, each of which occurs with the same relative frequency:

The probability distribution shown here describes a population of measurements
a. List all the different samples of n = 2 measurements that can be selected from this population.
b. Calculate the mean of each different sample listed in part a.
c. If a sample of n = 2 measurements is randomly selected from the population, what is the probability that a specific sample will be selected?
d. Assume that a random sample of n = 2 measurements is selected from the population. List the different values of x found in part b and find the probability of each. Then give the sampling distribution of the sample mean x in tabular form.
e. Construct a probability histogram for the sampling distribution of x.
