Answer:

Step-by-step explanation:

Let X be length of life of the participants in the plan.

Given that X is N(68,3.5)

We convert this to standard normal score z using

$z=\frac{x-68}{3.5}$

a) proportion of the plan recipients that would receive payments beyond age 75= $P(X\geq 75) = P(Z\geq 2)\\= 0.025$

b) proportion of the plan recipients die before they reach the standard retirement age of 65= $P(X\leq 65) = P(z\leq -0.86)\\=0.5-0.2764\\=0.2236$

c) x for 86% ceased

-14n + q=rt-4n, for n

pentagon [3]

N = -1/10rt + 1/10q
= −14n+q+4n=rt−4n+4n
= −10n+q=rt
= −10n+q+−q=rt+−q
= −10n=rt−q
= -10n/-10 = rt-q/-10
So the answer is:
= n = -1/10rt + 1/10q
