Suppose you are testing the null hypothesis that a population mean is greater than or equal to 60, against the alternative hypothesis that the population mean is less than 60. The sample size is 64 and alpha = 0.05. If the sample mean is 58 and the population standard deviation is 16, what is z value (test statistic) equal to?
