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. Follow the steps below to construct a 99% confidence interval for the population mean of all the weight gains for baby boys 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. (b) Take Sample Sample size: 0 Point estimate: Sample standard deviation: 0 Critical value: 0 Number of baby boys Compute 14 Sample mean 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 99% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute". 5.904 Standard error: Margin of error: Sample standard 99% confidence interval: deviation 1.611 X 3 Critical values 0.005 3.012 0.010 2.650 0.025 2.160 0.050 1.771 0.100 1.350 Based on your sample, graph the 99% confidence interval for the population mean of all the weight gains for baby boys in their first year.
