**Title: Birth Order Probability and Sampling Distribution in the United States (2014)****Introduction:**The 2015 National Vital Statistics Report provides insights into how nearly four million live births in the United States in 2014 were distributed across different birth orders. An analysis of these statistics can provide a better understanding of birth patterns during this period.**Birth Order Probability Table:**| Baby's Birth Order | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8+ ||--------------------|------|------|------|------|------|------|------|------|| Probability | 0.391| 0.319| 0.168| 0.072| 0.028| 0.012| 0.005| 0.005|**Interpretation:**- The table presents the probability of a randomly chosen baby being of a particular birth order.- Babies who are 9th or more in birth order are included in the "8" category.**Key Insight:**In 2014, 39.1% of the nearly four million live births in the United States were to first-time mothers.**Sampling Distribution:**The question examines the properties of the sampling distribution of the proportion of births to first-time mothers in random samples of 500 births from 2014.**Calculation Objectives:**- Determine the mean of the sampling distribution, rounded to three decimal places.- Calculate the standard deviation of the sampling distribution, rounded to four decimal places.**Conclusion:**Understanding these probabilities and the subsequent sampling distributions can yield valuable insights into family planning and demographic trends in the United States. These statistics are vital for researchers, policymakers, and educators focusing on population studies and maternal health.
