The Texas Instruments (TI-83/84) graphing calculators can compute the percentage of the population scoring higher than 31 using the syntax normalcdf(31,43,21.0, 5.3), given lower bound = 31, upper bound = 43, μ = 21.0, and σ = 5.3. The resulting value is 0.0296 or 2.96 percent (beginning on page 54). ................
