The answer depends on the distribution. But since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

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 two critical values of t from the t-distribution would you use to have 99 percent probability -area- for accepting the null hypothesis if you had df8?

91


The advantages of One-tailed and two-tailed test?

The choice of one-tailed or two-tailed tests follows the logic of the hypothesis that is being tested! The one-tailed test, if appropriate, will be more powerful.


Why is the type one error 0.0027?

The type I error is 0.0027 only when a two tailed test is used with a z-score of ±3. There are many occasions when a one-tailed test is more appropriate and with the same test would have half the Type I error. Furthermore, it is more usual for the researcher to specify the type I error first - 0.05, 0.01 or 0.001 are favourites - and to select one-or two-tailed critical region after that. It is, therefore, more likely that the Type I error is a "round" number (5%, 1% or 0.1%) while the critical z-score is not.


What is the difference between one-tailed and two-tailed test?

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


Why is an ANOVA test one-tailed?

The short answer is ANOVA is not one-tailed.

What is the indicated z score for 0.9693?

The one-tailed z-value is: P(Z < z) = 0.9693 => z = 1.8706


What is the advantage of a one-tailed test?

A one tailed test allows you to test a one-sided hypothesis.
