**Sample Comparison Exercise** In this exercise, two samples are taken with the following characteristics: - Sample 1: - Mean (\( \bar{x}_1 \)): 37 - Size (\( n_1 \)): 50 - Standard Deviation (\( s_1 \)): 5 - Sample 2: - Mean (\( \bar{x}_2 \)): 40 - Size (\( n_2 \)): 73 - Standard Deviation (\( s_2 \)): 4 **Task:** Estimate the difference in population means using a 91% confidence level. Use a calculator for the calculations, and do **not** pool the sample variances. Round your answers to the nearest hundredth. **Confidence Interval:** \[ < \mu_1 - \mu_2 < \] Fill in the values for the difference in population means.

![**Sample Comparison Exercise**
In this exercise, two samples are taken with the following characteristics:
- Sample 1:
- Mean (\( \bar{x}_1 \)): 37
- Size (\( n_1 \)): 50
- Standard Deviation (\( s_1 \)): 5
- Sample 2:
- Mean (\( \bar{x}_2 \)): 40
- Size (\( n_2 \)): 73
- Standard Deviation (\( s_2 \)): 4
**Task:**
Estimate the difference in population means using a 91% confidence level. Use a calculator for the calculations, and do **not** pool the sample variances. Round your answers to the nearest hundredth.
**Confidence Interval:**
\[
< \mu_1 - \mu_2 <
