Answer:
The correct answer is Option A.) The standard deviation of the distribution of sample means is less than the population standard deviation of the number of cancer spots.
Step-by-step explanation:
The standard deviation of the distribution of sample means is less than the population standard deviation of the number of cancer spots.
For this case we have that Newton's second law is given by:

Where:
m: It's the mass
a: Acceleration
F: It's the force
According to the data we have:

Dividing between 40,000 on both sides of the equation:

Thus, the acceleration is
