Write the normal probability for the shaded region of the graph and find its value. Select the correct choice below and fill in the answer box within your choice.
D. P(3x7)=P(2.5lx7.5)=
Expectation = np = 8.8
Variance = np(1 - p) = 3.96
Standard deviation = 1.990
Z value for 2.5, z=(2.5-8.8)/1.990 =-3.17
Z value for 7.5, z=(7.5-8.8)/1.990 =-0.65
P( -3.17<z<-0.65) = P( z < -0.65) – P( z < -3.17)
=0.2578-0.0008
=0.2570
