Let's calculate the **mean** and **standard deviation** for the given data set:

**Weights of the books**: {24, 23, 19, 17, 12, 14, 14, 28, 23}

### Step 1: Calculate the mean
The formula for the mean is:

\[
\text{Mean} = \frac{\text{Sum of all values}}{\text{Number of values}}
\]

\[
\text{Mean} = \frac{24 + 23 + 19 + 17 + 12 + 14 + 14 + 28 + 23}{9}
\]

Let's calculate it.

### Step 2: Calculate the standard deviation
The formula for standard deviation (for a sample) is:

\[
s = \sqrt{\frac{\sum (x_i - \mu)^2}{n - 1}}
\]

Where:
- \(x_i\) = individual data points
- \(\mu\) = mean of the data set
- \(n\) = number of data points

Now let's calculate the values.

Calculate the mean and standard deviation for the data set. Round to the nearest hundredth. Weights, in ounces, of nine books: {24, 23, 19, 17, 12, 14, 14, 28, 23}
