on an exam with a =70, you have a score of X=65. Which of the following values for the standard deviation would give you the highest position within the class? a) =1 b) =10 c) =5 d) not enough info Solution (x - µ) / s = z the highest z score will give you the answer (65 - 70) / 5 = z -1= z (65- 70) / 10 = z -.5 = z (65 - 70) / 1 = z -5 = z if s = 10 is answer.
