I am preparing for my finals and came across this question:
I am quite confused on this one since we have two unknowns. I tried using binomials distribution with with n being the number of patients to be vacinated in order to get at least 1000 successes, but i cannot calculate both and from the same equation.
is there any other approach to solve this problem? thank you.
Thank You. Thats what I was thinking about.
Apparently, the value of p had been missing in the question, which was p=90%(which was the major source of my trouble) and I was supposed to find "n" only. That makes life easy. I just used normal approximation to find n.
