Answer 1

Answer:

hello some details/parts of your question are missing attached below is the missing part

answer : A ) = 24.13%

              B ) =  0.1084, The preceding data series represents a SAMPLE        

              C ) =  0.4494

Explanation:

A) The average realized  return on FF stock can be calculated as

= 24% + 16.15% + 29% +39.9% + 12.35% / 5

= 24.13%

B) The preceding data series represents a SAMPLE  standard deviation BECAUSE RETURNS WERE MADE ONLY FOR FIVE YEARS

and the sample standard deviation is calculated as

$s^2 = \frac{summation ( x - mean vale)^2}{N-1}$

$S^2 = \frac{0.0470383}{ 5 -1 }$  =   0.01175056

s = $\sqrt{0.01175056}$ = 0.1084

C) coefficient of variation

coefficient of variation = standard deviation / mean

                                      = 0.1084 / 0.2413 = 0.4494
