Consider the data in listed in the table above.
- Assuming population variances are equal; construct an appropriate 95% confidence interval for the difference in mean Gestation Age between infants born in Hospital B and Hospital C.
- Provide an interpretation of the interval in part a.
- Assuming population variances are not equal; construct an appropriate 95% confidence interval for the difference in mean Gestation Age between infants born in Hospital A and Hospital B.
- Assuming the population variances are equal, construct an appropriate 90% confidence interval for the difference in mean Birth Weight between infants born in Hospital A and Hospital C.
- Provide an interpretation of the interval in part d.
