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.
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 75 percent confidence interval estimation?
1.15
What is the Z value for 95 percent confidence interval estimation?
1.96
What is the Z value for 99 percent confidence interval estimation?
ss
What is the z value for 86 percent confidence interval estimation?
Pr{z<=1.0805}~=0.86
What is z value for 90 percent confidence interval?

What is the critical value of z for an 88 percent confidence interval?
The two tailed critical value is ±1.55
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
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 z value is associated with the 99 percent confidence interval?
2.326 (one sided) or 2.578 (two sided)
