Final answer:
The mean age of Best Actor Oscar winners over the last eleven years is approximately 49.45 years old, calculated by summing the ages and dividing by the number of data points.
Step-by-step explanation:
To calculate the mean age for Best Actor winners over the last eleven years, you add the ages together and divide by the number of ages listed. The ages given are 55, 44, 32, 41, 41, 59, 37, 45, 83, 53, 54. The calculations would be as follows:
- Add all the ages together: 55 + 44 + 32 + 41 + 41 + 59 + 37 + 45 + 83 + 53 + 54 = 544.
- Divide the sum by the number of ages: 544 / 11 = 49.45.
The mean age of Best Actor Oscar winners over the past eleven years is approximately 49.45 years old. This calculation is a measure of central tendency, providing an average age around which the ages of the winners are distributed.
