Health care knowledge systems reported that an insured woman spends an average of 2.3 days in the hospital for a routine childbirth, while and uninsured woman spends an average of 1.9 days. Assume two samples of 16 women each were used in both samples. The standard deviation for the first sample in 0.6 day, and the other standard deviation of the second sample is 0.3 day. At the 0.01 significance level, test the claim that the means are equal.
