Solve for
|
The value for which to solve. Descriptions follow for the three choices that are available to you.
• Confidence Level. The confidence value to use to calculate the bounds and bounds ratio.
• Bounds Ratio. For the time at the specified usage level unreliability, the upper confidence bound divided by the lower confidence bound.
• Sample Size. The number of units tested.
The two choices not selected become the parameters for which you must supply values. Choices are:
• When Confidence Level is selected, Bounds ratio is the first parameter, and Confidence level is the second parameter. The defaults are 3 and 100, respectively.
• When Bounds Ratio is selected, Confidence level is the first parameter, and Sample size is the second parameter. The defaults are 0.95 and 100 respectively.
• When Sample Size is selected, When selected, Confidence level is the first parameter, and Bounds ratio is the second parameter. The defaults are 0.95 and 3 respectively.

[Parameter 1]
|
Depending on the value for which to solve, the first parameter value required for the calculation.
|
[Parameter 2]
|
Depending on the value for which to solve, the second parameter value required for the calculation.
|
[Result]
|
Shows the result calculated for the value for which to solve.
|
When clicked, the supplied parameter values and test plan data are used to calculate the result, which is shown in the display-only field to the left.
