Approximately 20% of U.S. workers are afraid that they will never be able to retire. Suppose 10 workers are randomly selected. a. How is X defined? What is the probability distribution of X? b. What is the probability that none of the 10 workers are afraid that they will never be able to retire? c. What is the probability that no more than two of the 10 workers are afraid that they will never be able to retire? Use table d. What is the probability that fewer than 8 of the 10 workers are NOT afraid that they will never be able to retire? e. Calculate the expected value, the variance, and the standard deviation of the probability distribution. What does it tell you?
