The time T between requests to a web server is exponentially distributed with mean 0.5 seconds.
(a) What is the value of the parameter in this exponential distribution? Give the p.d.f. and c.d.f. of T? [2]
(b) Use the c.d.f. of T to find the median request time and interpret it. [3]
(c) What is the probability that the request time is between 0.25 and 1.5 seconds? [1](
d) Find the 60th percentile of the request time and interpret it. [2]
