Question
The waiting time t (in minutes, after placing your order) at the local 'frituur' is given by the
density function f(t) = a (9.2-t) (t-6.8) when 6.8 ≤ t ≤9.2 and f(t) = 0 elsewhere.
a. Show that a = 125
288
b. Find the mean and the standard deviation for the waiting time.
c.
It is your unlucky day today: you have just placed your order, but it turns out you are
among the 10% of clients served slowest, what does this mean for your waiting time?
Also graph the density function and indicate the answer on this graph.
