Assume that adults have IQ scores that are normally distributed with a mean of 96.296.2 and a standard deviation 20.520.5. Find

Sergeeva-Olga [200]

Answer:

The first quartile of the IQ scores of adults is 82.26.

Step-by-step explanation:

The first quartile is the value that is greater than 25% of the observations and less than 75% of the observation.

The formula to compute the first quartile (Q₁) of a Normal distribution is:

$Q_{1}=\mu-0.68\sigma$

The mean and standard deviation of the IQ scores of adults are:

$\mu=96.2\\\sigma=20.5$

Compute the first quartile value as follows:

$Q_{1}=\mu-0.68\sigma=96.2-(0.68\times20.5)=82.26$

Thus, the first quartile of the IQ scores of adults is 82.26.
