# Question

Find the probability that a piece of data picked at random from a normal population will have a standard score (z) that lies between the following pairs of z-values:

a. to z = - 2.75 z = -1.38

b. to z = 0.67 z = 2.95

c. to z = - 2.95 z = -1.18

a. to z = - 2.75 z = -1.38

b. to z = 0.67 z = 2.95

c. to z = - 2.95 z = -1.18
