Question
A 95% confidence interval for µ1 − µ2 is given by (-2.3, 4.5). What can we infer from this confidence interval?
(a) This confidence interval implies that there is not a significant difference between the
(b) This confidence interval implies that the mean for population 1 is greater than the mean for population 2.
(c) This confidence interval implies that the mean for population 1 is less than the mean for population 2.
(d) This confidence interval implies that the mean for sample 1 is less than the mean for sample 2.
