In order to solve this problem, we will calculate the z-score of the given data.
To do this, we use the formula,
We plug in the given data:
With this z-score, we can consult a z-score probability table or use an online resource. However, this will give us
but we are interested in itbeing greater than it, so we must calculate
So, the percentage of the population that has an IQ above 154 is 0.224%.
