Compute the mean of the following data:

56, 42, 37, 29, 45, 51, 30, 25, 34, 57

A. 52.1
B. 42.8
C. 39.4
D. 40.6

Answer :

Correct answer- D 40.6
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.
