The probability of a war in the international system is normally distributed with a mean of 15 and a standard deviation of 8. How far are the following scores, in standard deviation units, from the population mean and give a one sentence interpretation of each result, i.e., what it means? Using the z score formula, calculate the probabilities associated with each of the following raw scores:
1) What is the probability of observing 12 wars or less?
2) What is the probability of observing more than 16 wars or less than 14 wars?
Please provide steps of how answer was reached.
