A discrete variable X can take on integer values of 1 to 10. A sample of size
Question:
A discrete variable X can take on integer values of 1 to 10. A sample of size 50 results in the following probability estimates:
(a) Write out and graph the cumulative distribution.
(b) Calculate the following probabilities using the cumulative distribution: X is between 6 and 10, and X has the values 4, 5, or 6.
(c) Use the cumulative distribution to show that P(X = 7 or 8) = 0.0. Even though this probability is zero, the statement about X is that it can take on integer values of 1 to 10. How do you explain the apparent contradiction in these twostatements?
