Q.9 The number of times a batter gets to bat in a game follows a binomial distribution N ∼ Binomial(6, 0.8). Given the number of times N = n that the better has at bat, the number of hits he gets conditionally follows a binomial distribution as well, (X|N = n) ∼ Binomial(n, 0.3)
(a) Find E[X]
(b) Find Var[X]
(c) Find Cov[X, N]
(d) Find ρ[X, N]

a player pays $2 to toss a coin 3 times. He gets $1 if the
number of tails is 2, and he gets $6 if the number of tails is 3,
but nothing otherwise. Let X be his reward based on the number of
tails.
1)What is the expected value of X?
2)What is his expected profit per game?
3)what is Var(X)?

A baseball player, Mickey, who bats 310 (or .310) gets an
average of 3.1 hits in ten at bats. We will assume that each time
Mickey bats he has a 0.31 probability of getting a hit. This means
Mickeys at bats are independent from one another. If we also assume
Mickey bats 5 times during a game and that x= the number of hits
that Mickey gets then the following probability mass function,
p(x), and cumulative distribution function F(x) are...

b. A rookie is brought to a baseball club on the assumption that
he will have a .300 batting average. (Batting average is the ratio
of the number of hits to the number of times at bat.) In the first
year, he comes to bat 300 times and his batting average is .267.
Could such a low average be considered just bad luck or should he
be sent back to the minor leagues? Assume that his at...
