First, we will find the z-score associated with a height of 26 inches. z-score = (x – μ) / σ = (26 – 26.5) / 2.5 = -0.5 / 2.5 = -0.2 Step 2: Use the z-table to find the percentage that corresponds to the z-score. Next, we will look up the value -0.2 in the z-table: We see that 42.07% of values fall below a z-score of -0.2. Web(symbol: φ) a measure of association for two dichotomous or binary random variables. The phi coefficient is the product-moment correlation coefficient when both variables are coded (0, 1).
