1. True False While there have long been attempts to reduce risk to concrete measures, we are not yet to the point where any one measure adequately describes risk in every situation.

b. True False Despite the development of more sophisticated approaches, sensitivity analysis and break even analysis continue to be useful tools.

c. True False The expected value is a commonly used measure of dispersion.

d. True False The standard deviation is expressed in squared units but the variance is expressed in the same units as the observations.

E. True False The standard deviation can combine hundreds of possible outcomes in a single risk statistic.

F. True False The coefficient of variation is calculated by dividing the standard deviation by the expected value.

G. True False Utility theory is a very useful tool and many corporations are spending many dollars mapping the utility functions of senior level executives and stockholders.
