Find the z-score for the height of 56 inches, b. What does the negative sign for the z-score represent? c. Is this observation a potential outlier according to the three standard deviation distance criterion? Explain a. Find the z-score z= (Round to one decimal place as needed.) b. What does the negative sign for the z-score represent? O A. The observation is not a potential outlier. O B. The observation is a potential outlier. O C. The observation is below the mean. O D. The observation is above the mean c. Is this observation a potential outlier according to the three standard deviation distance criterion? Explain O A. Yes, because the z-score is negative O B. No, because it is less than three standard deviations from the mean. O C. Yes, because it is greater than three standard deviations from the mean. O D. No, because the z-score is negative. 27'CZ O Q 9 0 6 GEFORCE COMET RTX
