According to the Sleep Foundation, the average night's sleep is 6.8 hours (Fortune, March 20, 2006). Assume the standard deviati

vivado [14]

Let $X$ be the random variable for the time a given person from the population spends sleeping. With $X\sim\mathcal N(6.8,0.4^2)$ we have

$P(X>8)=P\left(\dfrac{X-6.8}{0.4}>\dfrac{8-6.8}{0.4}\right)=P(Z>3)\approx0.0013$

where $Z\sim\mathcal N(0,1^2)$ .

$P(X\le6)=P\left(\dfrac{X-6.8}{0.4}\le\dfrac{6-6.8}{0.4}\right)=P(Z\le-2)\approx0.0228$

$P(7$

Rounded to the nearest whole number, that comes out to about 31%.
