Roughly 68% of the distribution is between z = -1 and z = +1, ie within 1 standard deviation of the mean. This is from the 68-95-99.7 rule or better known as the Empirical Rule. 

The final answer is choice D) 68.2%

Fiona is gathering signatures on a petition to save the Orangutans. If she gets 4 times the number of signatures that she has ri
Reika [66]

Answer: 2000

Step-by-step explanation:

Set up equation

The total signatures she needs is 4 times as many as she has. From this we can create the equation (4n = total signatures)

We know that the total number of signatures is 8000, so plug this into the equation to get 4n = 8000

Solve for n

Now that we have an equation, we can solve for n by dividing both sides by 4

4n = 8000

n = 8000 / 4 = 2000

Final Answer

Fiona has collected 2000 signatures so far
