Standard deviation is the square root of the variance. For the square root of a number to be greater than the number, the number must be between 0 and 1.
Hence, for the standard variation to be greater than the variance, the variance must be between 0 and 1.

Answer:
<u><em>6% decline</em></u>
Step-by-step explanation:
<u>Original stock price</u> = $3.63 + $56.87 = $60.50
