and the order in which they appear. An empty string ""
displays the default: all results, including headers. The options
in the configuration string are separated by spaces.
• h: header cells will be created
• Z: the critical Z-value
• zXl: the lower bound of the confidence interval
• zXh: the upper bound of the confidence interval
• zXm: the midpoint of the confidence interval
• std: the standard deviation
Example:
ConfZ2prop(21, 26, 50, 50, 0.95, "")
ConfT1mean The one-sample Student’s T confidence interval for a mean.
