The letter "t" makes up an estimated 9% of a certain language. Assume this is still correct. A random sample of 500 letters is taken from a randomly selected, large book and the t's are counted. Find the approximate probability that the random sample of 500 letters will contain 8.3% or fewer t's.

Expert Solution
Solution
Given that,
p = 0.09
1 - p = 1 - 0.09 = 0.91
n = 500
= p = 0.09
= 
=
P(
0.083) =
= P((
-
) /
(0.083 - 0.09)
/ 0.0128)
= P(z -0.5469)
= 0.2922
Probability = 0.2922

A certain basketball player makes 80% of his free throws. Assume
that results of successive free throws are independent of each
other. At the end of a particular practice session the coach tells
the player to begin shooting free throws and stop immediately after
the first unsuccessful shot. What is the probability that the
player will throw the ball at most four times?

Suppose the returns on long-term corporate bonds and T-bills are
normally distributed. Assume for a certain time period, long-term
corporate bonds had an average return of 5% and a standard
deviation of 8.3%. For the same period, T-bills had an average
return of 3.5% and a standard deviation of 2.5%. Use the NORMDIST
