The proportion of data between 161 cm and 197 cm is displayed as a decimal.
3. Use the normalcdf command with a standard normal distribution.
If the data points are z-scores, so that you are using a standard normal
distribution with mean 0 and standard deviation 1, you can omit the mean
and standard deviation from the argument and just enter the z-scores.
For example, to determine the area under the standard normal curve
between z-scores of �0.87 and �1.35,
