A health care company reported that an insured woman spends on average 1.94 days in the hospital for childbirth, while an uninsured woman spends an average of 1.21 days. Assume two samples of 15 women each were used in both samples. The standard deviation of the first sample is equal to .80 a day, and the second group is .40. At a= .0025, the objective is to test the claim that the means are equal. Round to two decimal places.
