Final answer:
To find the mean of the given data set {4, 12, 15, 15, 17, 18, 20, 24, 29}, sum all the numbers to get 154 and then divide by the number of values, which is 9, yielding a mean of approximately 17.11.
Step-by-step explanation:
The question asks to calculate the mean of the given data set {4, 12, 15, 15, 17, 18, 20, 24, 29}. The mean (also known as the average) is calculated by adding all the numbers in the set together and then dividing by the total number of values in the set.
To calculate the mean, we first sum up all the numbers:
4 + 12 + 15 + 15 + 17 + 18 + 20 + 24 + 29 = 154
Next, we divide this sum by the total number of values, which in this case is 9:
Mean = 154 / 9 ≈ 17.11
The mean of this data set is approximately 17.11.
