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

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

It depends on whether the interval is one sided or two sided. The critical value for a 2-sided interval is 1.75
Estimating the true value of a popular parameter typically involves statistical methods such as point estimation or interval estimation. Point estimation provides a single value as an estimate, while interval estimation offers a range within which the true value is likely to fall, often accompanied by a confidence level. Accurate estimates rely on representative samples and appropriate methodologies to mitigate biases and errors. Ultimately, the goal is to approximate the true parameter value as closely as possible based on available data.
