Consider a block of radio-active metal with a "half-life" of 1 day. Roughly speaking, this neans that after 1 day the amount of radiation is half of what it was at the beginning of the lay, after two days it is 1/4th, after three days 1/8th, etc. Let N; be the number of particles chat arrive at a Geiger counter during [0, t] (hours). (a) Is it reasonable to assume that (N;) is a Poisson process with time dependent rate A(t) = c x ()7 (t in hours), for some constant c (c is called the initial rate)? We put from now on c= 10 (per hour).

Consider a block of radio-active metal with a "half-life" of 1 day. Roughly speaking, this means that after 1 day the amount of radiation is half of what it was at the beginning of the day, after two days it is 1/4th, after three days 1/8th, etc. Let N; be the number of particles that arrive at a Geiger counter during [0, t] (hours). (a) Is it reasonable to assume that (Nt) is a Poisson process with time dependent rate (t) = cx ()724 (t in hours), for some constant e (c is called the initial rate)? t/24 We put from now on c = 10 (per hour).
