Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distribute
balu736 [363]

Answer:

The area of the shaded region is 0.9082.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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, which is the area of the shaded region, is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 100, \sigma = 15, X = 120

Area of the shaded region:

pvalue of Z

Z = \frac{X - \mu}{\sigma}

Z = \frac{120 - 100}{15}

Z = 1.33

Z = 1.33 has a pvalue of 0.9082

So

The area of the shaded region is 0.9082.
