Suppose that a discrete random variable is the number of broken eggs in a randomly selected carton of one dozen
eggs. the expected value for the number of broken eggs is 0.48 eggs. which of the following statements is a
correct interpretation of this expected value? explain why the others are wrong.
a. the probability that an egg will break in one-dozen cartons is 0.48, on average.
b. when a large number of one-dozen cartons of eggs are examined, the average number of broken eggs in a
one-dozen carton is 0.48 eggs.
c. the mean number of broken eggs in one-dozen cartons is 0.48 eggs

b. When a large number of one-dozen cartons of eggs are examined, the average number of broken eggs in a

one-dozen carton is 0.48 eggs

Step-by-step explanation:

given that a discrete random variable is the number of broken eggs in a randomly selected carton of one dozen  eggs. The expected value for the number of broken eggs is 0.48 eggs.

Here expected value we mean average and when we take a large number of one dozen eggs, the broken eggs would be approximately 0.48 eggs.

This is the application of central limit theorem to mean of sample of a random varaible.

Hence correct option is

b. When a large number of one-dozen cartons of eggs are examined, the average number of broken eggs in a

one-dozen carton is 0.48 eggs

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
