Answer :
Final answer:
The mean age of the people attending an appointment at a fracture clinic is calculated as the sum of their ages divided by the total number of individuals. By adding the ages and dividing by 10, the mean age is determined to be 33.1 years. Therefore, the listed options do not have the correct answer, and the actual mean should be referred to as the final answer. So the correct answer is none of the above.
Explanation:
To determine the mean age of the people attending an appointment at a fracture clinic with ages 8, 42, 12, 70, 15, 20, 4, 53, 87, and 20, we simply calculate the average. The mean is found by adding all the ages and dividing by the total number of ages. We can perform the calculation as follows:
- Add all the ages: 8 + 42 + 12 + 70 + 15 + 20 + 4 + 53 + 87 + 20 = 331.
- Divide the sum by the total number of people: 331 ÷ 10 = 33.1 years.
The mean age of people attending for an appointment at the fracture clinic is 33.1 years. This means that option B) 34.5 years is not correct since none of the provided options precisely match our calculation. However, the options might be a misprint or incorrect. The actual mean age we calculated should be considered the final answer.
