A Value of X May Be Converted to a Score $z = \frac { \bar { X } - \mu } { \sigma \bar { X } }$

question 45

Multiple Choice

A value of X may be converted to a score on the standard normal distribution by using the formula.

• A) \(z = \frac { \bar { X } - \mu } { \sigma \bar { X } }\)
• B) \(z = \frac { \bar { X } - \bar { X } \bar { A } } { \sigma _ { \bar { x } } }\)
• C) \(z = \frac { \bar { X } - \mu } { \sigma }\)
• D) \(z = \frac { \bar { X } - \mu } { \sigma ^ { 2 } }\)
