$\sigma = 0.5\ Seconds$

Step-by-step explanation:

Given that

Mean ,λ = 0.5 seconds

In exponential distribution ,variance is given as follows

Variance=λ²

Variance = 0.5 x 0.5 = 0.25 seconds

The standard deviation in exponential distribution is given as follows

$\sigma=\sqrt{Variance}$

$\sigma = \sqrt{0.25}$

$\sigma = 0.5\ Seconds$

Therefore the standard deviation will be 0.5 seconds.

14.4%

L*W*H=V=10*9*4.5=405 in^3.

that is 50.5 in^3 over the estimate, or 14.4%
