**Question:**A psychological introvert-extrovert test produced scores that had a normal distribution with a mean and standard deviation of 75 and 12, respectively. If we wish to designate the *highest* 16% as extroverts, what would be the proper score to choose as the cutoff point? (Round your answer to two decimal places.)**Answer Box:**[Empty Text Field] [Incorrect Answer Indicator (Red X)]**Button:**[USE SALT]
