26. Afriend commutes by bus to and fromwork six days per week. Suppose that waiting time is uniformly distributed between 0 and 10 min, and that waiting P1 0 Yn  u 0  e2 S0 times going and returning on various days are independent of one another. What is the approximate probability that total waiting time for an entire week is at most 75 min? Hint: Carry out a simulation experiment using statistical software to investigate the sampling distribution of To under these circumstances.

The idea of this problem is that even for an n as small as 12, To and should be approximately normal when the parent distribution is uniform.What do you think?
