Properties	Description
Type of Interval
Type of confidence interval	specifies the confidence interval to use in the analysis. The options available in the task depend on the confidence interval that you choose. For more information about each confidence interval, see the descriptions in About the Confidence Intervals Task.
Solve For
specifies the type of analysis. You can solve for these items: the probability of obtaining a confidence interval that is a half-width less than or equal to the value of the half-width total sample size Note: If you select One proportion as the confidence interval, the Total sample size option is not available.
Analysis Details
Select an interval	specifies whether to perform the analysis for a one-sided or two-sided interval. Note: If you select One proportion as the confidence interval, this option is not available.
Select an interval type	specifies the interval to use if you selected One proportion from the Type of confidence interval drop-down list.
Confidence Level
specifies the confidence level.
Half-Width
specifies the desired confidence interval half-width. The half-width is defined as the distance between the point estimate and a finite endpoint.
Standard Deviation
specifies the standard deviation.
Proportion
specifies the proportion if you selected One proportion as the confidence interval.
Sample Size
Allow fractional sample sizes	enables fractional input and output for sample sizes.
Sample size values	specifies the total sample size.
