Answer:
The area will be the area to the right of 40.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the area to the left of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X, that is, the area to the right of X.
In this question:
Using the definition above, more than 40 is the area to the right of 40.
So
The area will be the area to the right of 40.
