(f) Find the area under the standard normal curve that lies to the right of 0.44.
answer:

FOR ALL THE VALUES THE Z TABLE WILL BE REFERED AND VALUES WILL BE TAKEN FROM Z TABLE ONLY.

A) Z SCORE = -0.71 = 0.2389

Z SCORE = 2.29 = 0.9890

AREA = 0.9890 - 0.2389 = 0.7501

B) Z SCORE = -2.01 = 0.0222

Z SCORE = 2.03 = 0.9788

AREA = 0.9788 - 0.0222 = 0.9566

C) AREA TO THE LEFT MEANS LESS THEN

Z SCORE = 1.43

AREA = 0.9236

D) AREA TO THE LEFT MEANS LESS THEN

Z SCORE = -0.23

AREA = 0.4090
