Kemp · Answer 1

Step-by-step explanation:

a) P (80 < X < 110) for N (100,15)

Mean 100 sd=15

z F (x)

80 - 1.333333333 0.09121122

110 0.666666667 0.747507462

P (80
b. P (1.50 < X < 2.00) for N (0,1)

z F (x)

1.5 0.933192799

2 0.977249868

P (1.50 < X < 2.00) = 0.04406

c. P (4,500 < X < 7,000) for N (6000,1000)

6000 1000

z F (x)

4500 - 1.5 0.066807201

7000 1 0.841344746

P (4500
d. P (225 < X < 450) for N (600,100)

600 100

z F (x)

225 - 3.75 8.84173E-05

450 - 1.5 0.066807201

P (225
