Suppose that this year we select a random sample of 50 births. The conditions are not met for use of a normal model since the expected number of preterm births is only 6 (12% of 50). So we ran a simulation with p = 0.12. Suppose that the sample of 50 babies has 4 that are preterm. This is 8% of the sample. Do the data suggest that the percentage of preterm births in the U. S. is lower than 12% this year?
