Answer:
5
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
On average, how much error would be expected between the sample mean and the population mean?
This is the standard deviation of the sample. We have that 
. So
The answer is 5.

Answer:
Part 1: 30.35 runners
Part 2: 2024
Step-by-step explanation:
We will need to find an equation that best fits this data
- The equation of best fit for this data is y = 2.16x - 4291.81
Now in order to figure our part 1, we will need to plug in 2001 for our x value to solve for y and we get:
- y = 2.16(2001) - 4291.81 which then simplifies to y = 30.35
Then to figure out part 2, we need to plug in 80 (NOT 80,000 because the y-values are in thousands, meaning we only need to use the number 80) for our y-value and solve for x and we get:
- 80 = 2.16x - 4291.81
- Adding 4291.81 to both sides we get: 4371.81 = 2.16x
- Then dividing both side by 2.16 we get 2023.98 = x ≈2024
