# 3 no Español A notable indicator of a baby's health is the weight gained in the first year of the baby's life. Assume that the population of all such weight gains for baby boys is approximately normally distributed. A study claimed that the mean of this population is 8.744 kg. As a practicing pediatrician, you want to test this claim. So, you select a random sample of 14 baby boys, and you record the weight each gained in their first year. F3 Follow the steps below to construct a 99% confidence interval for the population mean of all the weight gains for baby boys in a list of formulas.) their first year. Then state whether the confidence interval you construct contradicts the study's claim.
