The sum of 200 observations is 14000, then the mean is______ .

Options

A. 150
B. 120
C. 70
D. 60

Answer

To find the mean of the given observations, we can follow these steps:

### Step 1: Identify the given values
- The sum of observations (S) = 14000
- The total number of observations (N) = 200

### Step 2: Write the formula for mean
The formula for the mean (M) is:
\[ M = \frac{S}{N} \]
where:
- \( S \) is the sum of all observations
- \( N \) is the total number of observations

### Step 3: Substitute the values into the formula
Now, we can substitute the values of \( S \) and \( N \) into the formula:
\[ M = \frac{14000}{200} \]

### Step 4: Perform the division
Now, we will perform the division:
\[ M = \frac{14000}{200} = 70 \]

### Step 5: State the final answer
Thus, the mean of the observations is:
\[ \text{Mean} = 70 \]
