I neeed help with all parts of this quesiton 4

**Statistical Analysis of Two Populations** **Sample Details:** Independent random samples were selected from two quantitative populations. Below are the details for the sample sizes, means, and standard deviations: - \( n_1 = n_2 = 70 \) - \( \bar{x}_1 = 125.3 \) - \( \bar{x}_2 = 123.8 \) - \( s_1 = 5.9 \) - \( s_2 = 6.1 \) **Tasks:** 1. **Construct a 95% Confidence Interval** for the difference in the population means \((\mu_1 - \mu_2)\). (Round your answers to two decimal places.) - [ ] to [ ] 2. **Find a Point Estimate** for the difference in the population means. - [ ] 3. **Calculate the Margin of Error.** (Round your answer to two decimal places.) - [ ]
