A club is established with 2000 members, 1000 of exact age 35 and 1000 of exact age 45 . You are given:
(i) Mortality follows the Standard Ultimate Life Table
(ii) Future lifetimes are independent
(iii) [math] N[/math] is the random variable for the number of members still alive 40 years after the club is established
Using the normal approximation, without the continuity correction, calculate the smallest [math]n[/math] such that [math]\operatorname{Pr}(N \geq n) \leq 0.05[/math].
