Health Care Knowledge Systems reported that an insured woman (Group 1) spends on average 3.6 days in the hospital for a routine childbirth, while an uninsured woman (Group 2) spends on average 1.9 days. Assume two samples of 18 women each were used in both samples. The standard deviation of the first sample is equal to 0.6 day, and the standard deviation of the second sample is 0.3 day. At =0.01, test the claim that the means are equal. Assume that the population variances are equal.   Required: Test Value Only the final answer should be rounded-off to TWO decimal places.
