We should gain investment return based on Marquitz model and real return of this portfolio in order to evaluate the
second hypothesis. The portfolio return in Marquitz model is obtained from weight average of assets return.

The return is as the following according to Marquitz model:
E
P
= ∑Wi
Ei
= ( 29% × 0 / 43) + (0% × 0 / 58) + (71% × / 01) =
0 / 318
The real return is obtained as of the following:.
E
P
= ∑Wi
Ei
= ( 37% × 0 / 43) + (58% × 0 / 20) + (0 / 5% + / 01) = 0 / 2756
Now we can evaluate the second hypothesis too and the result is that return of total assets based
on Marquitz model is different from the obtained weight according to this model and real amount
of these assets. As it is observed return in Marquitz model is equal to 0.31 percent and in the real
model it is equal to 0.27. In fact the second hypothesis is rejected too.

In order to test the third hypothesis we should obtain the amount of risk formed Marquitz model
and then compare it with the obtained risk. Based on Marquetz model:

We can compare this number with the obtained number from Marquitz model based on
minimization and analyze the third hypothesis. In fact these two amounts are equal to some
extent. It means that we can confirm the third hypothesis optimistically.
We can represent a table like the following in order to reach to the result of the fourth hypothesis and compare
amount of obtained variables from both portfolios with each other.
