Question

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

Answer 1

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
