The geometric mean for the above set of data given is: 1.1475 (Option B). See the explanation below.
The geometric mean can be defined as the average rate of return of a set of values obtained by multiplying the terms together.
Geometric mean is best suited for series with serial correlation, which is notably true for investment portfolios.

Answer:
0.1190
Step-by-step explanation:
If z = -1.18, the total area to the left under the standard normal curve is taken from the z-distribution table attached;
P(z < - 1.18) = 0.1190
Also, to the right of z = 1.18, we have;
P(z > 1.18) = 1 - P(z < 1.18)
From the second image attached from z-table, we have;
P(z > 1.18) = 1 - 0.8810
P(z > 1.18) = 0.1190
Thus, the total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is 0.1190
