Preterm birth means premature H0 points birth: Is the percentage of preterm births lower this vear? Suppose that this year we select 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 simulation with p 0.12.

B. 0 Yes; because sample proportions of 0.08 or less are unusual given the population proportion is 0.12, 0 No, because sample proportions of 0.08 or less are not Unusual if the proportion of preterm births in the population is 0.12, D. 0 No, because a 25.6% of the babies are preterm this year which is much higher than 12%,  #### Similar Solved Questions
