![### Lake Water Sample Analysis
The following analysis has been conducted on a lake water sample. Please provide the values for alkalinity (a), total hardness (b), carbonate (c), and non-carbonate hardness (d) for this sample.
- **Is this water hard?**
Type "1" for YES and "2" for NO (e).
- **Estimate the percent reliability of the analysis** (f).
**Instructions:** Answers for a, b, c, and d should be in units of mg/L CaCO3. Provide all answers with three significant digits, except for (e).
**Tip:** Use the formula %diff = ((X-Y)/((X+Y)/2)) * 100 for calculations.
