**Transcription of Educational Content and Analysis**

The analysis of business start-up times involves assessing the average number of days required to complete the necessary procedures to legally operate a business in 20 developed and 20 emerging countries. Below is the detailed approach to this analysis:

**Section A: Hypothesis Testing**

We are tasked with determining if there is a significant difference in the mean time required to start a business between developed and emerging countries, assuming equal population variances. The significance level (α) is set to 0.05.

**Definitions:**
- μ₁: Mean time required to start a business in developed countries.
- μ₂: Mean time required to start a business in emerging countries.

**Hypotheses:**
- Null Hypothesis (H₀): μ₁ = μ₂ (The mean times are equal.)
- Alternative Hypothesis (H₁): μ₁ ≠ μ₂ (The mean times are not equal.)

**Test Statistic:**
- Calculated t-statistic (t_STAT) is 1.75, rounded to two decimal places.

**Critical Value:**
Selection choice is indicated for determining the critical value.
- Option A: tα/2 = ± (Requires input)

**Graphical Representation:**

The accompanying table presents data on the number of days to start a business:
- **Developed Countries (days):** 25, 115, 7, 33, 9, 6, 19, 7, 26, 8, 24
- **Emerging Countries (days):** 30, 10, 17, 14, 6, 12, 7, 21, 3

These numerical values represent the variation in business start-up times, highlighting both similarities and differences in procedural durations across different economic classifications of countries. The analysis helps in understanding economic development impacts on business operations.

**Conclusion:**
This exercise is part of a larger statistical investigation aimed at determining the efficiency and challenges associated with starting businesses across various global regions, enhancing strategic economic planning and policy formulation.

The critical value is yet to be determined and should be calculated or input based on standard statistical tables. Further analysis can explore the factors contributing to the differences in start-up times between the two categories of countries.
