Let X follow Demoivre with ω.
Find the distribution of T(x)
Let Z represent the present value random variable representing
benefit of $1 payable at the moment of death for a
whole life insurance sold to (x)- a person age x. Calculate E(Z)
and Var(Z).
Let W represent the present value random variable representing
benefit of $1 payable at the end of year of death
for a whole life insurance sold to (x)- a person age x. Calculate
E(W) and...
Find all distinct roots (real or complex) of
z2+(−6+i)z+(25+15i). Enter the roots as a comma-separated list of
values of the form a+bi. Use the square root symbol '√' where
needed to give an exact value for your answer. z = ???
Let z be a random variable with a standard normal
distribution.
Find “a” such that P(|Z| <A)= 0.95
This is what I have:
P(-A<Z<A) = 0.95
-A = -1.96
How do I use the symmetric property of normal distribution to make
A = 1.96?
My answer at the moment is P(|z|< (-1.96) = 0.95
