Z-Score: Definition, Calculation and Interpretation - Simply Psychology

WebThe z-score corresponding to 0.5987 is 0.25. Thus, the 60th percentile is z = 0.25. Now that we found the z-score, we can use the formula to find the value of x. The Z-score formula is z = x − μ σ. Using algebra, we can solve for x. x = μ + z ( σ) x = 70 + ( 0.25) ( 13) = 73.25 WebThe distribution for z is the standard normal distribution; it has a mean of 0 and a standard deviation of 1. For Ha: p ≠ 26, the P-value would be P (z ≤ -1.83) + P (z ≥ 1.83) = 2 * P (z ≤ -1.83). Regardless of Ha, z = (p̂ - p0) / sqrt (p0 * (1 - p0) / n), where z gives the number of standard deviations p̂ is from p0. ( 4 votes) tahseen1995 sail ships
