Questions:
Find the area under the normal curve in each of the following cases.

1. to the right of z = 1.63

2. between z = −1.36 and z = 2.55

3. to the left of z = −1.78

4. between z = −2.76 and z = −1.25

5. between z = 1.56 and z = 2.51​



ANSWER:

1. Z=1.63 = 0.4484
0.5-4484=0.0516

2. Z= -1.36= 0.4131
Z= 2.55 = 0.4946
0.4131+0.4946 =0.9077

3. Z= -1.78= 0.4625
0.5-0.4625=0.0375

4. Z=-2.76= 0.4971
Z= 1.25= 0.3944
0.4971-0.3944= 0.1027

5. Z=1.56=0.4406
Z= 2.51=0.4940
0.44.6-0.4940=0.0534
