## Educational Content: Analyzing Accounting Firm Data **Overview** A recent survey highlighted the top accounting firms across 10 geographical regions in country X, where the top 2 regions reported combined growth rates of 19% and 18%. The following analysis focuses on the number of partners within these firms. You are presented with data on the number of partners for 20 firms in each region and are asked to perform a statistical analysis. **Objective** At a 0.05 level of significance, investigate whether there is a difference in the mean number of partners between the two regions' accounting firms. **Hypothesis Formulation** Define: - \( \mu_1 \): Mean number of partners for the region with the highest growth. - \( \mu_2 \): Mean number of partners for the second highest growth region. Choose the correct hypotheses to test: - Option A: - \( H_0: \mu_1 = \mu_2 \) - \( H_1: \mu_1 \neq \mu_2 \) - Option B: - \( H_0: \mu_1 \geq \mu_2 \) - \( H_1: \mu_1 < \mu_2 \) - Option C: - \( H_0: \mu_1 \leq \mu_2 \) - \( H_1: \mu_1 > \mu_2 \) - Option D: - \( H_0: \mu_1 \neq \mu_2 \) - \( H_1: \mu_1 = \mu_2 \) Selected Hypotheses: Option A **Data Provided** - For the region with the highest combined growth: - Partners per 20 firms: 73, 101, 29, 38, 29, 32, 38, 32, 34, 12, 9, 7, 9, 12, 17, 25, 11, 25, 29, 9 - For the region with the second highest combined growth: - Partners per 20 firms: 171, 47, 53, 31, 65, 53, 51, 33, 47, 32, 19, 21, 32, 27, 35,
