Explanation / Answer

Solution:

From the given information

Sample size n = 288
Sample number of events D = 16
Sample proportion p = D/n = 16/288 = 0.0555
Sample proportion p0 = 0.10
= 0.01
test statistic z = p - p0/sqrt(p0(1-p0)/n) = [0.0555- 0.10]/sqrt[0.10(1-0.10)/288]
= -2.52
P-value = 0.00585
