For each value of z*, find the cumulative probability P(Z< or equal to z*). (Round all answers to four decimal places.)

z*=0
z*=0.3
z*=-0.3
z*=1.84
z*=-2.38
z*=2.78
z*=1.67

you may need to use the table for standard normal probabilities

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions related to these Z scores.

z* = 0, p = .5000
