Study Notes
Population and Sample Symbols
- The symbol for population mean is represented by mu (μ).
- Population standard deviation is denoted by sigma (σ).
- The symbol for population proportion is p.
- Sample mean is indicated by x bar (x̄).
- Sample standard deviation is represented by s.
- Sample proportion is shown as p hat ( p̂ ).
Point Estimates
