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 is the critical value of z for a 96 percent confidence interval?
The critical value of z for a 96 percent confidence interval is approximately 2.05. This value corresponds to the point where the area in each tail of the standard normal distribution is 2 percent, leaving 96 percent in the center. It is typically found using z-tables or statistical software.
How do you calculate confidence interval from odds ratio?
To calculate a confidence interval (CI) from an odds ratio (OR), you first need the natural logarithm of the OR (ln(OR)) and the standard error (SE) of the ln(OR). The CI can then be derived using the formula: CI = exp(ln(OR) ± Z * SE), where Z is the Z-value corresponding to the desired confidence level (e.g., 1.96 for 95% CI). Finally, exponentiate the lower and upper bounds to obtain the CI for the OR itself.
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 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
