On an IQ test,m= 100 ands = 15.

1. Let's find the area under the curve based on the raw score:

1. What percentage of people scored 120 or more?
2. What percentage of people score 94 or more?
3. What percentage of people scored 86 or lower?
4. What percentage of people scored 109or lower?
5. What percentage of people score between 103 and the mean?
6. What percentage of people scored between 92 and the mean?
7. What percentage of people scored between 90 and 106?
8. What percentage of people scored between 105 and 110?

2. Let's find the scores that correspond to various percentiles (remember, a percentile tells the percentage of people that an individual has scored the same or higher than).

1. 90^th percentile
2. 84^th percentile
3. 63^rd percentile
4. 50^th percentile
5. 46^th percentile
6. 10^th percentile
