The mean of the data 8,0,3,3, 1, 7, 4, 1, 4, 4 is:

Options

A. 3
B. 3.5
C. 3.75
D. 3.25

Answer

To find the mean of the given data set, we will follow these steps:

### Step 1: List the data
The data provided is: 8, 0, 3, 3, 1, 7, 4, 1, 4, 4.

### Step 2: Count the number of observations
Count the total number of values in the data set.
- There are 10 values in total.

### Step 3: Calculate the sum of the observations
Add all the numbers together:
- \( 8 + 0 + 3 + 3 + 1 + 7 + 4 + 1 + 4 + 4 = 35 \)

### Step 4: Divide the sum by the number of observations
Now, we divide the total sum by the number of observations to find the mean:
- Mean = \( \frac{Total \, Sum}{Number \, of \, Observations} = \frac{35}{10} = 3.5 \)

### Step 5: State the mean
The mean of the data set is 3.5.
