Fantastic news! We've Found the answer you've been seeking!
Question:
- What is the z statistic and what qualifies a statistic to be a z statistic based on the central limit theorem and the basic properties of normal distributions? What are the limitations of the central limit theorem, and how some of these limitations are bypassed?
- For example, the z statistic is the sampling distribution in estimating a proportion. What is the sampling distribution in estimating the variance of a population? What are the properties of this distribution? What is the alternative of the z statistic for normally distributed populations which eliminates some limitations of the central limit theorem? How is this sampling distribution constructed as a combination of a z distribution and a chi-squared distribution? What are the properties of this distribution?
