IQ Scores. In Exercises 1– 8, assume that adults have IQ scores that are normally dis- tributed with a mean of 100 and a standard deviation of 15 (as on the Weschler test). (Hint: Draw a graph in each case.)

 

1.   Find the probability that a randomly selected adult has an IQ that is less than 115.

 

2.   Find the probability that a randomly selected adult has an IQ greater than 131.5 (the requirement for membership in the Mensa organization).

 

3.   Find the probability that a randomly selected adult has an IQ between 90 and 110 (re- ferred to as the normal range).

 

4.   Find the probability that a randomly selected adult has an IQ between 110 and 120 (referred to as bright normal).

 

5.   Find P20, which is the IQ score separating the bottom 20% from the top 80%.

 

6.   Find P80, which is the IQ score separating the bottom 80% from the top 20%.

 

7.   Find the IQ score separating the top 15% from the others.

8.   Find the IQ score separating the top 55% from the others
