WebThe probability that a randomly selected adult from this group has an IQ greater than 128.1 is (Round to four decimal places as needed.) Question Transcribed Image Text: Assume … WebJan 2, 2024 · Since IQ scores are assumed to be normally distributed, this suggests that we can convert this to a standard normal z score. Letting z = (x - mu) / sigma, we have z = (134.6 - 102.5) / 17.6 = 32.1 / 17.6 = 1.82. From a z-statistic table, we can see that P (Z > 1.82) = 0.5 - 0.4656 = 0.0344.
