If the mean of a population is 34 and you randomly draw a single observation equal to 100 , without knowing s.d. we can conclude: The \( z \)-score is at least 2 . The z-score is greater than 0 . This observation is an outlier. All of the above, Question 3 2 pts If population mean equals 90 and the standard deviation equals 20 , a score of \( X=95 \) has a z-score equal to: \( 0.025 \) \( 0.25 \) \( -2.5 \) \( 2.5 \) None of the above
