Consider a Poisson process with rate λ=4, and let N(t) be the number of arrivals during the time interval [0,t].
Suppose that you have recorded this process in a movie and that you play this movie at twice the speed. The process that you will be seeing in the sped-up movie satisfies the following (pick one of the answers):
a) is a Poisson process with rate 2
b) is a Poisson process with rate 4
c) is a Poisson process with rate 8
d) is not a Poisson process
