Asupervisor finds the mean number of miles that the employees in a department live from work. he finds x=29 and s=3.6 . which statement must be true? z37 is within 1 standard deviation of the mean. z37 is between 1 and 2 standard deviations of the mean. z37 is between 2 and 3 standard deviations of the mean. z37 is more than 3 standard deviations of the mean.

Option 3 is right

z37 is between 2 and 3 standard deviations of the mean.

Step-by-step explanation:

Let X be a random variable which represents the mean number of miles that the employees in a department live from work

X is normal (N(29,3.6)

WE have to find Z score for X

Z =

=2.22

i.e. 37 is 2.22 std deviations from the mean.

In other words, z37 is between 2 and 3 standard deviations of the mean.

ian gonna lie that is way to much

the equation is going to be
