Question
Applying the Normal Distribution and Central Limit meorem
The population of adult women in the United States has a mean height of 65 inches (5'5") and a
standard deviation of 3.5 inches.
Let X = the height of an American female.
Thus, X~ N(65, 3.5).
Use the scenario above to determine the selected probabilities below. You may wish to use the
Normal Distribution Calculator hosted by the University of lowa's Department of Mathematical
Sciences. Remember: the formatting of this calculator may vary slightly from what is used in class.

a. What is the probability of randomly selecting a female shorter than 58 inches tall?
P(X < 58) =
(Include five decimal places.)
b. Determine the 90th percentile for the distribution. (This Normal Distribution Percentile
Calculator may be useful.)
X =
inches. (Include one decimal place.)
c. If 100 women were randomly chosen, what is the probability that the sample mean of this
group would be less than 64.5 inches?
P(X < 64.5) =
=
(Include five decimal places.)
