The heights of 7 players in a group are
175 cm, 158 cm, 180 cm, 164 cm, 182 cm, 160 cm and 171 cm. Find their mean height

Options

A. 165 cm
B. 170 cm
C. 133 cm
D. 156 cm

Answer

To find the mean height of the 7 players, we will follow these steps:

### Step 1: List the heights of the players.
The heights of the players are:
- 175 cm
- 158 cm
- 180 cm
- 164 cm
- 182 cm
- 160 cm
- 171 cm

### Step 2: Add all the heights together.
We will add the heights:
\[ 175 + 158 + 180 + 164 + 182 + 160 + 171 \]

Calculating the sum:
\[ 175 + 158 = 333 \\ 333 + 180 = 513 \\ 513 + 164 = 677 \\ 677 + 182 = 859 \\ 859 + 160 = 1019 \\ 1019 + 171 = 1190 \]

So, the total sum of the heights is **1190 cm**.

### Step 3: Count the total number of players.
The total number of players is **7**.

### Step 4: Calculate the mean.
To find the mean, we will divide the total sum of the heights by the number of players:
\[ \text{Mean} = \frac{\text{Total Sum of Heights}}{\text{Number of Players}} = \frac{1190}{7} \]

Calculating the division:
\[ 1190 \div 7 = 170 \]

### Final Answer:
The mean height of the players is **170 cm**.
