Next, you can use your z-table to find the probability of obtaining a z-value this large or larger. (Note: this corresponds to the probability of obtaining a sample mean of 580 or larger from a sample of 10 peoplerandomly selected from a population with a mean of 555.)
What is the probability of a Z score of .57 or more?
a) p = 0.2157
b) p = 0.7157
c) p = 1.0000
d) p = 0.0500
e) p = 0.2843
