Final answer:
The net present value of not testing is -$4.5 million and the net present value of testing is $1.5 million. The company should perform the test to verify the amount of oil under the ground.
Step-by-step explanation:
To determine whether it is worth paying for the test, we need to find the net present value (NPV) of testing and not testing.
If the company performs the test, the present value of cash flows from drilling will be $7 million (62% chance of 13 million barrels). Subtracting the $5.5 million drilling cost, the NPV of testing is $1.5 million.
If the company does not perform the test, the present value of cash flows will be $1 million (38% chance of 6 million barrels). Subtracting the $5.5 million drilling cost, the NPV of not testing is -$4.5 million.
Therefore, the net present value of not testing is -$4.5 million and the net present value of testing is $1.5 million. Since the NPV of testing is positive, the company should perform the test to verify the amount of oil under the ground.
