What is the probability of randomly selecting a zscore less than z = 0.80 from a normal distribution?
a)0.2119
b)0.7881
c)0.2119
d)0.7881

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to your Z score.
Hint: probability can only be positive.
