The Tennessee Health Department is concerned about average baby length. We know that the national baby birth length average is 20 inches. In our 2019-2022 cohort (n=613,836), we found that the Shelby County babies were on average 19.1 inches with a variance of 1.44 inches. Use hypothesis testing to determine if this is different from the national average (use significance level of 0.05).
