Health Care Knowledge Systems reported that an insured woman spends on average 2.3 days in the hospital for routine childbirth, while an uninsured woman spends on average 1.9 days. Assume two random samples of 16 women each were used in both samples. The population standard deviation of insured women is equal to 0.6 day, and the population standard deviation of uninsured women is 0.3 day. Find the 99% confidence interval for the differences of the means.
