The number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Furthe

antoniya [11.8K]

Answer:

D. 8

Step-by-step explanation:

We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.

As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.

So we can set an equation as:

$72-56=2\sigma$ or

$40-56=-2\sigma$

$16=2\sigma$

$\frac{16}{2}=\frac{2\sigma}{2}$

$8=\sigma$

$40-56=-2\sigma$

$-16=-2\sigma$

$\frac{-16}{-2}=\frac{-2\sigma}{-2}$

$8=\sigma$

Therefore, the standard deviation for our given data is 8 and option D is the correct choice.
