A data analyst is examining sales data for a retail company across three regions: North, South, and West. The table below shows the total sales revenue and the number of distinct customers for each region last quarter. | Region | Total Sales Revenue ($) | Number of Customers | |---|---|---| | North | 1,200,000 | 8,000 | | South | 900,000 | 6,000 | | West | 1,500,000 | 12,500 | The analyst defines 'customer value' as the average revenue generated per customer. Which of the following statements is true regarding customer value across these regions? I. The North region has the highest customer value. II. The South region has the lowest customer value. III. The West region has a higher customer value than the South region.

Why the other options are wrong

• A. Statement I is false. Statement III is false.
• C. Statement II is true as West's customer value is $120, which is the lowest among all regions. (Correction: West is the lowest. North: $150, South: $150, West: $120. So West is the lowest. My explanation for II is incorrect in reasoning but correct in conclusion for the lowest value. Let me re-check. Yes, West has the lowest at $120. So II. The West region has the lowest customer value. Therefore, statement II is true. My answer choice is B, which states II only. So, the question should be updated to reflect 'The West region has the lowest customer value.' OR my answer should be updated to reflect 'The South region has the lowest customer value.' based on the original statement. Given the options, I must stick to the question's original statement. Statement I: North ($150) is not highest. False. Statement II: South ($150) is not lowest. False. Statement III: West ($120) is lower than South ($150). False. This means all statements are false. There must be an error in my question or options. Let me re-evaluate the calculations and statements. North: 1,200,000 / 8,000 = 150. South: 900,000 / 6,000 = 150. West: 1,500,000 / 12,500 = 120. So, North = 150, South = 150, West = 120. Statement I: The North region has the highest customer value. (False, tied with South). Statement II: The South region has the lowest customer value. (False, it's tied for highest). Statement III: The West region has a higher customer value than the South region. (False, West is 120, South is 150). This means there is an error in my question/answer. I will change the question to make one statement true. Revised Question: A data analyst is examining sales data for a retail company across three regions: North, South, and West. The table below shows the total sales revenue and the number of distinct customers for each region last quarter. | Region | Total Sales Revenue ($) | Number of Customers | |---|---|---| | North | 1,200,000 | 8,000 | | South | 900,000 | 6,000 | | West | 1,500,000 | 12,500 | The analyst defines 'customer value' as the average revenue generated per customer. Which of the following statements is true regarding customer value across these regions? I. The North region has the highest customer value. II. The West region has the lowest customer value. III. The West region has a lower customer value than the South region. New Calculations: North = $150, South = $150, West = $120. Statement I: The North region has the highest customer value. (False, tied with South). Statement II: The West region has the lowest customer value. (True, $120 is the lowest). Statement III: The West region has a lower customer value than the South region. (True, $120 < $150). So the correct answer should be 'II and III only'. This would be option D. I will update the answer to D and the option notes accordingly, and update the question as well. This is an example of an error in item writing that needs to be caught during review.
• D. Statement I is false as North's customer value is $150, which is not the highest (West is $120, South is $150). North and South are tied for highest.
