Question
**Determine a 99% Confidence Interval for the Difference in Means (\(\mu_1 - \mu_2\))**

**Given Data:**

- Sample 1 (\(n_1\)): 50
  - Sample Mean (\(\bar{x}_1\)): 2.03
  - Sample Standard Deviation (\(s_1\)): 0.4

- Sample 2 (\(n_2\)): 45
  - Sample Mean (\(\bar{x}_2\)): 2.52
  - Sample Standard Deviation (\(s_2\)): 0.98

**Task:**
Calculate the 99% confidence interval for the difference between population means \(\mu_1 - \mu_2\) based on the sample information. Use appropriate statistical technology and round the final result to two decimal places.

**Procedure:**
- Calculate the standard error of the difference in means.
- Determine the critical value (z or t) for a 99% confidence level.
- Compute the margin of error and confidence interval.

**Link:** Use the provided technology link for calculations.

\([ \ \text{Calculated Interval} \ ] ± \ \text{Margin of Error}\)

**Instructions:** Round the answers to two decimal places.
