APFIVE The table below provides summary statistics for two independent samples. Which of the following correctly lists the sequence of steps for constructing a 95% confidence interval for the difference between the two population means?
| Sample Group | Sample Size (n) | Mean (x̄) | Standard Deviation (s) |
|---|---|---|---|
| Group 1 | 30 | 12.3 | 3.5 |
| Group 2 | 30 | 7.6 | 3.4 |
