Assume that the population of all such weight gains for baby girls isapproximately normally distributed. A study claimed that the mean of this population is 5.28 kg. As a practicing pediatrician, you want to test this claim. So, youselect a random sample of 13 baby girls, and you record the weight each gained in their first year.Follow the steps below to construct a 95% confidence interval for the population mean of all the weight gains for baby girls in their first year.
