URGENT!!!!!Driving times for students' commute to school is normally distributed, with a mean time of 14 minutes and a standard

LuckyWell [14K]

Answer:

B. 68%.

Step-by-step explanation:

We have been given that driving times for students' commute to school is normally distributed, with a mean time of 14 minutes and a standard deviation of 3 minutes.

First of all, we will find z-score of 11 and 17 using z-score formula.

$z=\frac{x-\mu}{\sigma}$

$z=\frac{11-14}{3}$

$z=\frac{-3}{3}$

$z=-1$

$z=\frac{17-14}{3}$

$z=\frac{3}{3}$

$z=1$

We know that z-score tells us a data point is how many standard deviations above or below mean.

Our z-score -1 and 1 represent that 11 and 17 lie within one standard deviation of the mean.

By empirical rule 68% data lies with in one standard deviation of the mean, therefore, option B is the correct choice.
