1. **Duplicates are more accurate than relying on a single data point.**
   - **True**: Using duplicates allows for the identification of outliers and provides an average value, which increases the accuracy compared to a single measurement that might be affected by random error.

2. **Duplicates are not as reliable as triplicates, especially if the points are not concordant.**
   - **True**: Triplicates provide a more robust dataset, allowing for better statistical analysis and error detection. If duplicates are not concordant, it is harder to determine which value is erroneous without additional data points.

3. **Duplicates involve a 33% decrease in reagent use when compared to using triplicates.**
   - **True**: Triplicates use 50% more reagent than duplicates. If duplicates use 2 units of reagent, triplicates use 3 units, representing a 33% decrease in reagent use when opting for duplicates instead of triplicates.
