What does the z-value in statistics have to do with the level of confidence?

A z-value by itself, has nothing to do with level of confidence.A z-value can be used to calculate probabilities of observing a result that is at least as far from the mean. That probability measure can be used to calculate the level of confidence but you need to be careful about using the one-tailed or two-tailed measures - as appropriate.A z-value by itself, has nothing to do with level of confidence.A z-value can be used to calculate probabilities of observing a result that is at least as far from the mean.

What z value corresponds to a confidnece level of 86?

The value for a one-sided confidence interval of 86% is 1.08


What does z equal for an a equals 0.01 and a lower level test?

For a lower level test with significance level (alpha) 0.01, the z value is -2.33. That is, P( z < -2.33) = 0.01. The area to the left of -2.33 is 0.01.


What is z value for 76 percent ci?

The answer will depend on whether the confidence interval is one-sided, or two-sided and, if two-sided, whether or not it is symmetrical. Symmetrical 2-sided: ±0.189


What is the value of a 'z' score of 0?

A z-score of 0 means the value is the mean.
