Options

A. 12.9
B. 12.8
C. 12.4
D. 13

Answer

To find the total height of 8 women given their mean height, we can follow these steps:

### Step 1: Understand the concept of mean
The mean height is calculated by dividing the total height by the number of individuals. In this case, the mean height of the 8 women is given as 1.60 m.

### Step 2: Use the formula for mean
The formula for mean is:
\[ \text{Mean} = \frac{\text{Total Height}}{\text{Number of Individuals}} \]
We can rearrange this formula to find the total height:
\[ \text{Total Height} = \text{Mean} \times \text{Number of Individuals} \]

### Step 3: Substitute the values
We know:
- Mean height of women = 1.60 m
- Number of women = 8

Now, we can substitute these values into the formula:
\[ \text{Total Height} = 1.60 \, \text{m} \times 8 \]

### Step 4: Calculate the total height
Now, perform the multiplication:
\[ \text{Total Height} = 1.60 \times 8 = 12.8 \, \text{m} \]

### Conclusion
The total height of the 8 women is 12.8 meters.
