Answer: False
Explanation:
By definition, the z-score of the random variable, x, is
[tex]z = \frac{x - \mu}{\sigma} [/tex]
where
μ = the population mean
σ = the population standard deviation
Because only the sample mean and the sample standard deviations are known, we cannot calculate the z-score. Instead, we can calculate the Student t-test statistic.
