Question
Transcribed Image Text:Assume a standardized IQ test exists that possesses a normal distribution and has a mean score
of 100 with a standard deviation of 5. Answer the following questions:
13. What is the z score for an IQ score of 104 (use the provided z-score table on pg.4)?
You will now need to use Table A2 in your text to answer the following questions. What is the
probability of selecting someone from the general population at random who would:
14. Score between 104 and 100?
