Suppose that the scores of a reference population on the Wechsler Inteligence Scale for Children (WISC) can be modeled by a NORMAL distribution with mean 101 and standard deviation 17 Question 1. What is the probability that a child has a WISC score BELOW 76.47 (use 4 decimal places in your answer Question 2. What is the probability that a child has a WISC score ABOVE 146.47 (use & decinul places in your answer) Question 3. What is the probability that a child has a WISC score BETWEEN 101 and 121 67 (use 4 decimal places in your answer) Question 4. What are the quartiles of WISC scores? (HINT: First Quartile Q1- Find a WISC score such that 25% of children have scored below that score. Third Quartie Q3- Find a WESC score such that 75% of students have scored below that score) Q₁- 2-
