Using the Central Limit Theorem · Exercise 31
The time to wait for a particular rural bus is distributed uniformly from zero to 75 minutes. One hundred riders are randomly sampled to learn how long they waited.
Would you be surprised, based on numerical calculations, if the sample average wait time (in minutes) for 100 riders was less than 30 minutes?
(a) yes
(b) no
(c) There is not enough information.
Its source prints no answer for this problem, so there's nothing to check against.
