Mean ( u ) =0
Standard Deviation ( sd )=1
Normal Distribution = Z= X- u / sd ~ N(0,1)
To find P(a < = Z < = b) = F(b) - F(a)
P(X < -1.3) = (-1.3-0)/1
= -1.3/1 = -1.3
= P ( Z <-1.3) From Standard Normal Table
= 0.0968
P(X < 1.4) = (1.4-0)/1
= 1.4/1 = 1.4
= P ( Z <1.4) From Standard Normal Table
= 0.91924
P(-1.3 < X < 1.4) = 0.91924-0.0968 = 0.8224
