The answer will depend on whether the interval in one or two sided.

One-sided: Z < 1.28 or Z > -1.28

Two-sided: -1.64 < Z < 1.64

What is z value for 90 percent confidence interval?

For a two-tailed interval, they are -1.645 to 1.645


What is the Z value for 67 percent confidence interval estimation?

The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114The answer will depend on whether the interval is one-sided or two-sided; and if two-sided, whether it is symmetrical.For a symmetrical two-sided confidence interval, the Z value is 0.974114


When determining the 95 percent confidence interval for a population mean with known sigma the value of the critical value of z is equal to?

1.96


The width of a confidence interval is equal to twice the value of the margin of error?

No. The width of the confidence interval depends on the confidence level. The width of the confidence interval increases as the degree of confidence demanded from the statistical test increases.


When comparing the 95 percent confidence and prediction intervals for a given regression analysis what is the relation between confidence and prediction interval?

Confidence interval considers the entire data series to fix the band width with mean and standard deviation considers the present data where as prediction interval is for independent value and for future values.
