• A) Provided that the sample size n is large, the standardized variable \(Z = ( \bar { X } - \mu ) / ( \sigma / \sqrt { n } )\)
• Is approximately normally distributed, while the variable \(Z = ( \bar { X } - \mu ) / ( S / \sqrt { n } )\)
• Is not.
• B) The formula \(\bar { x } \pm z _ { \alpha/2 } \cdot s / \sqrt { n }\)
• Is a large-sample confidence interval for \(\mu\)
• With confidence level approximately \(100 ( 1 - \alpha ) \%\)
• )
• C) Generally speaking, n >40 will be sufficient to justify the use of the formula \(\bar { x } \pm z _ { \alpha/2 } \cdot s / \sqrt { n }\)
• As a large-sample confidence interval for \(\mu\)
