Statistics

Assume that Thomas is a new student in a similar school system to those we’ve talked about in our previous examples, which has classes for gifted and learning-disabled students and uses an IQ test with: µ = 100 and σ = 15.

Thomas needs to be tested to see if he is significantly different from normal.  Using a

 z-test for scores,  test at = .05             

Thomas gets an 86 on the IQ test.
