A database lists 15 potential suppliers with fields: 'Supplier ID', 'Product Category', 'Certification (ISO 9001, LEED, None)', 'Location (Domestic, International)', 'Average Delivery Time (Days)', 'Cost Score (1-5, lower is better)'. How many suppliers offer 'Domestic' products, have 'ISO 9001' certification, and an 'Average Delivery Time' of 10 days or less?
✓ Correct Answer: Option B
To answer this, you would filter the hypothetical table by three criteria: Location = 'Domestic', Certification = 'ISO 9001', and Average Delivery Time <= 10 days. The correct count would then be derived from the filtered results. For example, if the data were: S1 (Dom, ISO, 8), S2 (Int, ISO, 12), S3 (Dom, None, 7), S4 (Dom, ISO, 10), S5 (Dom, ISO, 15), S6 (Dom, LEED, 9), S7 (Dom, ISO, 6), then the count would be 3 (S1, S4, S7).
