... To calculate the cumulative probability of a binomial distribution, use the binomial cumulative distribution function. Find this command by pressing 2ND [DISTR] and selecting binomcdf( from the DISTR menu. The syntax is binomcdf(n, p, k). For example, for the example on pages 384–385 of the student ...

... Simple IDA methods can provide much commonsense guidance in this area. The human eye-brain combination detects patterns and trends much more easily in graphical form than when the data are presented as a list of numbers. So calibration and other graphs should always be inspected visually, and dot-pl ...
