Answer :
To find the mean of the given data set, follow these steps:
1. List the Data Points: The data points given are 56, 42, 37, 29, 45, 51, 30, 25, 34, and 57.
2. Calculate the Sum of the Data Points: Add all the data points together.
- [tex]\( 56 + 42 + 37 + 29 + 45 + 51 + 30 + 25 + 34 + 57 = 406 \)[/tex].
3. Count the Number of Data Points: There are 10 data points in the list.
4. Compute the Mean: The mean is the sum of the data points divided by the number of data points.
- Mean = [tex]\(\frac{406}{10} = 40.6\)[/tex].
Therefore, the mean of the data is 40.6.
The correct answer is d. 40.6.
