In the formula for Z -test statistic \(Z=\frac{\bar{x}-\mu_0}{\sigma / \sqrt{n}}\), mark the incorrect statement.
- A \(\bar{x}\) is sample mean
- B \(\mu_0\) is population mean
- C \(n\) is sample size
- D \(\sigma\) is variance of the population
Answer & Solution
Correct Answer
(D) \(\sigma\) is variance of the population
Step-by-step Solution
Detailed explanation
The incorrect statement is: σ is variance of the population. σ is the population standard deviation.
