QUESTION 28
Consider this question: For a certain set of data, what percentage of individuals would have a zscore less than 1.45?
(Hint: this is asking what percentage of the normal curve would fall less than that zscore.)

This discussion introduces you to normal probability via the calculated zscore. A zscore converts a nonstandard normal distribution into a standard normal distribution; a standard normal distribution has a mean of zero and standard deviation of one.
