The Z-value for a one-sided 91% confidence interval is 1.34
1.96
Pr{z<=1.0805}~=0.86
The answer depends on whether the test is one-tailed or two-tailed.One-tailed: z = 1.28 Two-tailed: z = 1.64
The two tailed critical value is ±1.55
The Z-value for a one-sided 91% confidence interval is 1.34

Pr{z<=1.0805}~=0.86
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
For a two-tailed interval, they are -1.645 to 1.645
The answer depends on whether the test is one-tailed or two-tailed.One-tailed: z = 1.28 Two-tailed: z = 1.64
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
The two tailed critical value is ±1.55
1.96
It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75
2.326 (one sided) or 2.578 (two sided)
