Answer 1

Solution:

We are required to determine the area under the standard normal curve that lies to the left of the given z- values.

Since the area lies to the left, the required area will be p(x < Z)

(a) Z = 0.37

p(x<0.37) = 0.64431

(b) Z=1.37

p(x<1.37) = 0.91466

(c) Z = 0.29

p(x<0.29) = 0.61409

(d) Z= -1.12

p(x< -1.12) = 0.86864
