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