1,Suppose a bus arrive at a bus stop every 20 minute and that
the waiting time for the next bus to arrive as a uniform probability distribution on the interval
from 0 to 20 minute.
a,compute the mean and standard deviation of the persons waiting time x.what is the probability that x were seen 10 minute
b,The probability density function of time x required to compute an assembly operation is uniformly distributed for the interval
30</x</40

i,Determine the proportion of assembly that requires less than 35 sec to complete
ii,what time is exceeded for the waiting time x

1/2? You REALLY need help on this problem? Have you been going to class?

Apply this to the bus problem. Show us what you get and how you got it.
