Question

C. Find the probabilities for each, using the standard normal distribution.

a). P(0<z<1.69) = _________ b). P(-2.46<z<1.74) = ___________

D. Find the standard z score value below:

a). 53.98% of the area under the distribution curve lies to the left of z. ___________

b). 82.12% of the area under the distribution curve lies to the right of z. ____________

c). Find the two z scores so that 44% of the middle area is bounded by them_______

E. Find the area under the standard normal distribution curve for the problems

a) To the right of z=1.10

b) Between z=-1.12 and z=0.24

c) To the left of z=2.11

C)Solution:

a)P(0<z<1.69)

P (0<z<1.69) = 0.454486

b). P(-2.46<z<1.74)

If the z table values are based on standard normal distribution between mean and values of z

Then P(z=1.74) =0.4591

P(z=-2.46) =0.4931

P(-2.46<z<1.74)=0.9522
