Explanation:

a) Data and Calculations:

Time     Marsh   ARR

1              ​$99      

2             141       42. 4% ($42/$99 * 100)

3             121       -14.2% (-$20/$141 * 100)

4             88        -27.3 (-$33/$121 * 100)

5             99        12.5 ($11/$88 * 100)

Sum of ARR =   13.4%

Arithmetic mean = 3.35% (13.4%/4)

Geometric mean = {(1 + 0.424 * 1 - 0.142 * 1 - 0.273 * 1 + 0.125)∧1/4} - 1

= {(1.424 * 0.858 * 0.727 * 1.125)∧1/4} - 1

= {(0.99927)∧1/4} - 1

= 0.2498 - 1

= -0.7502
