According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual.
Part B.
Find the probability that the person is between 64 and 69
inches.
Write the probability statement.
What is the probability? (Round your answer to four decimal places.)
Sketch the graph.
Part C.
Would you expect to meet many Asian adult males over 74 inches? Explain why or why not, and justify your answer numerically.
---Select--- Yes No , because the probability that an Asian male is over 74 inches tall is.
Part D.
The middle 40% of heights fall between what two values?
Write the probability statement.
P(x1 < X < x2) =
State the two values. (Round your answers to one decimal place.)
x1 | = | |
x2 | = |
