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 the value of a 'z' score of 0?
A z-score of 0 means the value is the mean.
What 3 elements are used to calculate a confidence interval?
A confidence interval is calculated using three key elements: the sample mean, the standard deviation (or standard error) of the sample, and the critical value from the relevant statistical distribution (such as the z-score or t-score) corresponding to the desired confidence level. The formula combines these elements to estimate the range within which the true population parameter is expected to lie, given the sample data. This interval provides a measure of uncertainty around the sample estimate.
What is the Z value for 99 percent confidence interval estimation?

What z value corresponds to a confidnece level of 86?
The value for a one-sided confidence interval of 86% is 1.08
What is the Z value for 91 percent confidence interval estimation?
The Z-value for a one-sided 91% confidence interval is 1.34
What is the z value for 86 percent confidence interval estimation?
Pr{z<=1.0805}~=0.86
What Z value corresponds to a confidence level of 88 percent?
1.555 With 88% confidence, there is 6% (0.06) in either tail of the standard Normal distribution. Table C will not help here. Using Table A the correct z* is about halfway between 1.55 and 1.56. According to technology, z*=1.555
What is the critical z value thst corresponds to a confidence level of 88 percent?
The answer will depend on whether the critical region is one-tailed or two-tailed.
What is the critical z value that corresponds to a confidence level of 92 percent?
It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75
What is the Z value for 95 percent confidence interval estimation?
1.96
