A researcher in the West Coast of the US wants to estimate the amount of newly discovered antibody in human blood. His research funds will only let him obtain blood samples from a random sample of 41 people, so he decides to construct a 95% confidence interval to estimate the mean antibody level in the population. Another researcher on the East Coast of the US is researching the same antibody, but has more research funding and is able to obtain blood samples from a random sample of 121 people. The East Coast researcher also creates a 95% confidence interval for the population mean. How will their confidence intervals compare?
