An individual being tested for a gifted program scores a 132 on the Cognitive Ability Test (CogAT), which has a mean of 100 and a standard deviation of 16. There is a .40 correlation between the CogAT score and success as measured by GPA in the gifted program, which has a weighted mean of 4.3 with a SD of .2. Use the Standard Error of the Estimate (SEest) to predict where this students GPA will fall 68 percent of the time.
