Buses on a particular route stop in front of De Anza College every 20 minutes between 3:00 p. m. and 1:00 a. m. The waiting times are equally likely. We asked the 33 people waiting at 6:45 p. m. how long they had been waiting, and then calculated the average wait time for those people. The probability that the average wait time is no more than 15 minutes is:.
a. 1.
b. 0. 7500.
c. 0. 7769.
d. 0.
The distribution of the average wait times is:
a. N(10 , 1. 0050).
b. U(0 , 20).
c. N(10 , 5.7735).
d. Exp (1 20).
