Question 910579: A certain chromosome defect occurs in only 1 in 230 adult Caucasian males. A random sample of n = 100 adult Caucasian males is to be obtained.
(a) What is the mean value of the sample proportion p̂, and what is the standard deviation of the sample proportion? (Enter your mean as an exact integer, fraction, or decimal. Round your standard deviation to five decimal places.)
mean=?

standard deviation=?
(b) Does p̂ have approximately a normal distribution in this case? Explain.
Yes, because np < 10 and n(1 − p) < 10.
Yes, because np > 10 and n(1 − p) > 10.
No, because np < 10.
No, because np > 10.
.
(c) What is the smallest value of n for which the sampling distribution of p̂ is approximately normal?
n = adult Caucasian males
