**MathGuru**, Friday, January 25, 2013 at 5:22pmUse the normal approximation to the binomial distribution.

mean = np

standard deviation = √npq

Therefore:

mean = .94n

standard deviation = √(n)(.94)(.06) = √(.0564n)

Using z-scores:

z = (x - mean)/sd

With the data:

1.645 = (160 - .94n)/√(.0564n)

Solve for n.

(Hint: Round answer to 165.)
