Answer 1

a).

Distribution Plot Normal, Mean=0, StDev=1 Density 0.3131 0 X 0.45 2.22

From the above normal probability plot, the required probability is 0.3131.

b).

Distribution Plot Normal, Mean=0, StDev=1 0.9320 Density -1.6 -1.6 2.22

From the above normal probability plot, the required probability is 0.932.

c).

Distribution Plot Normal, Mean=0, StDev=1 0.2716 Density -1.6 -0.45

From the above normal probability plot, the required probability is 0.2716.
