Scores on an IQ test are normally distributed with mean 96 points and standard deviation 16 points. Complete parts (a) through (c) below. a. According to the classification, a person with an IQ score between 110 and 120 points has superior intelligence. Find the probability that a randomly selected person has superior intelligence. P(110<x< 120) = 0.1240 (Round to four decimal places as needed.) b. According to the classification, a person with an IQ score less than 60 points has extremely low intelligence. Find the probability that a randomly selected person has extremely low intelligence. P(x<60) = 0.0122 (Round to four decimal places as needed.) c. Find the probability that a randomly selected person does NOT have extremely low intelligence. P(x ≥60) = (Round to four decimal places as needed.)
