Answer:
the best guess is 14.4%
Step-by-step explanation:
The computation of the best guess for the rate of return on the stock is shown below
Before
11% = α + [6% × 1] + [5% × 0.8]
11% = α + 6% + 4%
α = 1%
Now With the changes:
= 1% + [7% × 1] + [8% × 0.8]
= 1% + 7% + 6.4%
= 14.4%
Hence, the best guess is 14.4%
