A heаlth mаnаgement firm has samples оf satisfactiоn ratings frоm former patients of two hospitals, and wants to know if one is rated more highly than the other. The information will be used to refer patients and to make suggestions for hospital improvement. The variances of the two samples were found to be sufficiently similar, so a pooled standard deviation will be used for the test. Two-Sample T-Test and CI: Rate, Hospital Equal variances are assumed for this analysis.
