![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 girls is
approximately 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, you
select 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. Then state
whether the confidence interval you construct contradicts the study's claim. (If necessary, consult a list of formulas.)
(a) Click on "Take Sample" to see the results for your random sample.

Sample mean

5.656
1.939
Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the critical value you need for your 95%
confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute".
