# Analyze Unusual Baby Growth Patterns using Confidence Intervals

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

In order to identify baby growth patterns that are unusual, we need to construct a confidence interval estimate of the mean head circumference of all babies that are 2 months old. a random sample of 100 babies is obtained and the mean head circumferene is found to be 40.6cm. Assuming that the population standard deviation is known to be 1.6cm. Find a 95% confidence interval estimate for the mean head circumference of all two-month old babies. What aspect of this problem is not realistic?
