Raw Score (X): Population Mean (μ): Standard Deviation (σ): WebT/F: For a sample with a standard deviation of s = 10, a score with a deviation of +5 will have a z-score of z = 0.50. True T/F: For a population of exam scores, a score of X = 83 corresponds to z = +0.50 and a score of X = 89 corresponds to z = +1.50. The population mean is m = 80.
