Find the average of the following set of scores
152,635,121,423,632,744,365,253,302

Options

A. 403
B. 396
C. 428
D. 383

Explanation

To find the average of the given set of scores, we will follow these steps:

### Step 1: List the scores
The scores provided are:
- 152
- 635
- 121
- 423
- 632
- 744
- 365
- 253
- 302

### Step 2: Calculate the sum of the scores
We need to add all these scores together.

\[ \text{Sum} = 152 + 635 + 121 + 423 + 632 + 744 + 365 + 253 + 302 \]

Calculating the sum step-by-step:

1. \(152 + 635 = 787\)
2. \(787 + 121 = 908\)
3. \(908 + 423 = 1331\)
4. \(1331 + 632 = 1963\)
5. \(1963 + 744 = 2707\)
6. \(2707 + 365 = 3072\)
7. \(3072 + 253 = 3325\)
8. \(3325 + 302 = 3627\)

So, the total sum of the scores is \(3627\).

### Step 3: Count the number of scores
The total number of scores is \(9\).

### Step 4: Calculate the average
To find the average, we divide the total sum by the number of scores.

\[ \text{Average} = \frac{\text{Sum}}{\text{Number of scores}} = \frac{3627}{9} \]

Calculating the division:

\[ \text{Average} = 403 \]

### Final Answer
The average of the given set of scores is **403**.
