Critical Value for the standard normal distribution: a z-score separating unlikely values from those that are likely to occur. Notation: denotes the z-score with an area of α to its right. α is the Greek letter alpha. Remember that Table A-2 lists cumulative areas to the left of a given z-score, so use 1 – α to find

2. Find the Z score by looking up the percentile rank in Table 1. 3. Convert the Z score of 1.65 into an X, using Corty’s Equation 4.2 (X = µ + (Z * σ) (p105) X = 100 + (1.65*15) = 124.75 or 125 since IQ scores are reported to the nearest whole number. Extreme percentages exercise on p. 123
