Area to the left of z-scores = 0.6000. The closest value in the table is 0.5987. The 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.
