9. If a sample is large enough that np > 10 and n(1-p) >
10 are both true, then the probability of a result can be
estimated using the z-score. If this z-score method is
used for a sample with n = 40 trials, and p = 0.45, then
what value of x must be used in the z-score calculation
to estimate P(x > 29)?
