Extracted text: The table shows population statistics for the ages of Best Actor and Best Supporting Actor winners at an awards ceremony. The distributions of the ages are approximately bell-shaped. Compare the z-scores for the actors in the following situation. Best Actor Best Supporting Actor μ 42.0 H = 54.0 o = 8.7 O = 13 In a particular year, the Best Actor was 39 years old and the Best Supporting Actor was 83 years old. Determine the z-scores for each. Best Actor: z = -0.34 Best Supporting Actor: z = 2.23 (Round to two decimal places as needed.) Interpret the z-scores. The Best Actor was less than 1 standard deviation below the mean, which is not unusual. The Best Supporting Actor was more than 2 standard deviations above the mean, which is unusual.
