1. In the statement, "Based on the period 1950 1999, you would have the less uncertainty about any expected return on small company stocks than you would about the expected return on 3-month T-Bills.", changing "3-month T-Bills" to "large company stocks" would result in the statement being True.

2. In the statement, "Our author discusses the average return and standard deviation for 3 different assets for the period 1950 1999.", changing "3" to "4" would result in the statement being True.

3.In the statement," Diversifiable risk, Company-specific risk, Systematic risk and Market risk all refer to the same type of risk.", changing "Systematic" to "Unsystematic" would result in the statement being True.

4.In the statement, "By diversifying you can eliminate most or all of Systematic risk.", changing "Systematic" to "Unsystematic" would result in the statement being True. In the statement, "The variance is the square root of the standard deviation.", switching "variance" and "standard deviation" would result in the statement being True.

5.In the statement, "A stock with one-half the average market risk would have a value for beta of 2.0.", changing "2.0" to "0.5" would result in the statement being True.

8.In the statement, "To find the standard deviation, we take the square root of the sum of the deviations of each observation from the mean of the observations.", changing "deviations" to "squared deviations" would make the statement True.

9. In the statement, "When working with the entire population of observations, the denominator of the variance calculation is (n -1).", changing "(n - 1)" to "n" would result in the statement being True. In the statement, "Ceteris paribus, higher standard deviations represent lower risk.", changing "higher" to "lower" would result in the statement being True.
