the time between customer visits to the bank from midday to 1pm is evenly distributed over the period from 0 to 120 seconds. what is the standard deviation of the timeout?

Respuesta :

Using the uniform distribution, the standard deviation of the timeout is of 34.64 seconds.

What is the uniform probability distribution?

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The standard deviation is:

[tex]S = \sqrt{\frac{(b - a)^2}{12}}[/tex].

For this problem, the bounds are:

a = 0, b = 120.

Hence the standard deviation is found as follows:

[tex]S = \sqrt{\frac{(120 - 0)^2}{12}} = 34.64[/tex].
