A researcher wants to estimate the mean number of hours per day that elementary aged school children spend watching TV in order to direct subsequently planned research in reducing time spent watching TV among young children. She collects a sample of 424 children and calculates a 95% confidence interval for number of hours per day spent watching TV: Confidence interval = (1.93, 4.25).

What is the correct interpretation of this confidence interval?
