1. Assume that you have a normal distribution of IQ scores with a mean of 100 and a standard deviation of10
2. What is the z score for a raw score of 115?

Z =

1. What is the z score for a raw score of 83?

Z =

1. What is the z score for a raw score of 70?

Z =

1. What proportion (percentage) of the cases has an IQ score above 115?

1.Z for 115 =

2.Percentage (after checking table value) =

3.100 - the value you got for 2 =

1. What is the probability that you would find an IQ score of 70 or below

1.Z for 70 =

2.Calculate percentile value which is the score below 70 =

1. What is the probability that you would find an IQ score of 125 or above?

1.Z for 125 =

2.Find percent value from table =

3.100 - answer for 2 =
