17. Find the probability that a piece of data from a standard normal distribution will have a standard score described by the following:
a) Less than z = 1.25
b) Between z = – 2.03 and z = – 0.69
c) Find the score associated with the 62nd percentile
Refer Standard normal table/Z-table to find the probability or use excel formula "=NORM.S.DIST(1.25, TRUE)" to find the probability.
