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, HospitalEqual variances are assumed for this analysis.Descriptive Statistics: Rate Hospital N Mean StDev SE Mean A 10 80.7 10.6 3.4 B 15 59.0 14.2 3.7 Estimation for Difference Difference PooledStDev 95% Lower Boundfor Difference 21.7 12.92 12.66 Test Null hypothesis H₀: μ₁ - µ₂ = 0 Alternative hypothesis H₁: μ₁ - µ₂ > 0 T-Value DF P-Value 4.11 23 0 Estimation for Difference Difference 21.700 95% CI for Difference (11.397, 32.003) Report the values of the difference in sample mean ratings for the two hospitals and test statistic.
