Assume That Y Is Normally Distributed N(?, ?²) $\frac { c _ { 1 } - \mu } { \sigma }$

Multiple Choice

Assume that Y is normally distributed N(?, ?²) . To find Pr(c₁ ? Y ? c₂) , where c₁ < c₂ and d_i = $\frac { c _ { 1 } - \mu } { \sigma }$ , you need to calculate Pr(d₁ ? Z ? d₂) =

A) ?(d₂) - ?(d₁)
B) ?(1.96) - ?(1.96)
C) ?(d₂) - (1 - ?(d₁) )
D) 1 - (?(d₂) - ?(d₁) )
