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)? 29 O 28 O 30 O 29.5 28.5
