The correct Answer is:
To find the mean age of the 10 teachers, we will follow these steps: ### Step 1: List the ages of the teachers The ages of the 10 teachers are: - 32, 44, 53, 47, 37, 54, 34, 36, 40, 50 ### Step 2: Calculate the sum of all the ages We need to add all the ages together: - Sum = 32 + 44 + 53 + 47 + 37 + 54 + 34 + 36 + 40 + 50 Calculating this step-by-step: - 32 + 44 = 76 - 76 + 53 = 129 - 129 + 47 = 176 - 176 + 37 = 213 - 213 + 54 = 267 - 267 + 34 = 301 - 301 + 36 = 337 - 337 + 40 = 377 - 377 + 50 = 427 So, the total sum of the ages is **427**. ### Step 3: Count the total number of observations The total number of teachers (observations) is **10**. ### Step 4: Calculate the mean The mean is calculated by dividing the sum of the ages by the total number of observations: - Mean = Sum of ages / Total number of observations - Mean = 427 / 10 = 42.7 ### Final Result The mean age of the teachers is **42.7 years**. ---
