Find the mean of
28,24, 37,42,56,59,67,28,15 and 32.

Answer

To find the mean of the numbers 28, 24, 37, 42, 56, 59, 67, 28, 15, and 32, follow these steps:

### Step 1: Arrange the numbers in ascending order.
The given numbers are:
28, 24, 37, 42, 56, 59, 67, 28, 15, and 32.

Arranging them in ascending order gives:
15, 24, 28, 28, 32, 37, 42, 56, 59, 67.

### Step 2: Calculate the sum of the numbers.
Now, we need to sum all the numbers in the arranged list:
\[ 15 + 24 + 28 + 28 + 32 + 37 + 42 + 56 + 59 + 67 \]

Calculating this step-by-step:
- \( 15 + 24 = 39 \)
- \( 39 + 28 = 67 \)
- \( 67 + 28 = 95 \)
- \( 95 + 32 = 127 \)
- \( 127 + 37 = 164 \)
- \( 164 + 42 = 206 \)
- \( 206 + 56 = 262 \)
- \( 262 + 59 = 321 \)
- \( 321 + 67 = 388 \)

So, the sum of all the numbers is \( 388 \).

### Step 3: Count the number of terms.
The number of terms in the list is \( 10 \).

### Step 4: Calculate the mean.
The mean is calculated by dividing the sum of the numbers by the number of terms:
\[ \text{Mean} = \frac{\text{Sum of all terms}}{\text{Number of terms}} = \frac{388}{10} = 38.8 \]

### Final Answer:
The mean of the given numbers is \( 38.8 \).
