WebThe most common formula to calculate a Z score involves the observation (X), the hypothesized mean (μ), and hypothesized standard deviation (σ): Enter any number for Z to calculate the P value from Z score statistics. Entering your Z score as positive or negative will result in the same P value, because this test is two-sided. http://et.engr.iupui.edu/~skoskie/ECE302/hwAsoln_06.pdf
