Question

1) Which of the following statements is false? A) The variance increases with the magnitude of the deviations from the mean. B) The variance is the expected square deviation from the mean. C) Two common measures of the risk of a probability distribution are its variance and its standard deviation. D) If the return is risk-free and never deviates from its mean, the variance is one.

Answer 1

Answer:

D) If the return is risk-free and never deviates from its mean, the variance is one.

Explanation:

In the given case, the following statements are true:

a. In the case when the variance increased so the deviation magnitude from the mean is also increased

2. The variance is the predicted square deviation from the mean

3. And, the two common measures of the risk is the variance and the standard deviation

But when the return is risk less so the variance should be zero not one

Therefore the option d is false
