$10,724.29

Step-by-step explanation:

The mean is basically the average of the 7 numbers shown. To get the average, we need to add all the numbers & divide by the number of numbers (which in our case is 7 numbers). Thus, we have:

Mean =

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
