A 95% confidence interval for μA -μg is given by (-2.3, 4.5). What can we infer from this confidence interval? (A) This confidence interval implies that the mean for sample A is less than the mean for sample B. (B) This confidence interval implies that the mean for sample A is equal to the mean for sample B. (C) With 95% confidence, there is convincing statistical evidence that the mean for population A is less than the mean for population B. (D) With 95% confidence, there is convincing statistical evidence that the mean for population A is greater than the mean for population B. (E) There is not convincing statistical evidence that the mean for population A is different from the mean for population B at the 5% significance level.
