- For a Standard normal Distribution, Find:
P (Z < -1.2)
From the normal tables, P (Z < -1.2) =0.1151
- For a Standard normal Distribution, Find:
P (Z > 1.6)
Since the included furthest ends make no difference for continuous variable;
From the standard normal table
- For a Standard normal Distribution, Find:
P (-2.36 < Z < -0.61)
P (-2.36 < Z < -0.61) = P (Z < -0.61) –P (Z < -2.36)
= 0.2709−0.0091= 0.2618
So;
P (-2.36 < Z < -0.61) = 0.2618
- For a Standard normal Distribution, Find:
P (Z < 2.27)
From the standard normal table, P (Z < 2.27) = 0.9884
- For a Standard normal Distribution, Find:
P (Z > 2.63)
Since the included furthest ends make no difference for continuous variable;
From the standard normal table
- For a Standard normal Distribution, Find:
P (-0.31 < Z < 2.16)
P (-0.31 < Z < 2.16) = P (Z < 2.16) –P (Z < -0.31)
= 0.9846−0.3783= 0.6063
So;
P (-0.31 < Z < 2.16) = 0.6063
