ANSWER:Step 1 of 4
Let the number of defects on a roll of magnetic recording tape has a Poisson distribution with mean , where is either or . The prior p.d.f. of is
- Let random variable represents the number of defects on a roll of magnetic recording tape.
- A randomly selected roll of tape has 3 defects.
We need to find the posterior p.d.f of .
