Answer:
b. False
Step-by-step explanation:
The utility score assigned by an investor to a particular portfolio is influenced by various factors, including not only the expected return but also the risk or variability associated with the portfolio. The standard deviation is a measure of risk or volatility. In general, investors often prefer portfolios with higher expected returns and lower standard deviations, as it indicates a better risk-return trade-off.
Therefore, as the standard deviation decreases (indicating lower risk), other things being equal, the utility score assigned by an investor is more likely to increase, not decrease.
