Exercise

Calculating areas with sample means (2)

In the last exercise, we calculated the area under the curve right of our sample mean of 26. We found that this area had a probability of 0.023. Let's visualize this:

You may notice that this distribution of sample means is much narrower than the distribution of observations of individual hipsters. How would you interpret the red area?

Possible Answers

The red area is the probability of obtaining a hipster with a mean beard length equal or larger than 26.
The red area is the probability of obtaining a sample with a mean beard length equal or larger than 26 millimeter based on a sample of 50 hipsters.
The red area constitutes a probability of 1
