Another one Igimoh — let's solve it. The image explains the concept of the Arithmetic Mean or Simple Mean. Step 1: Understand the definition of the Arithmetic Mean. The arithmetic mean, denoted as $\bar{x}$ (read as "x bar"), is a measure of central tendency. It is calculated by summing all the values in a dataset and then dividing by the total number of values in that dataset. Step 2: State the formula for the Sample Mean. The formula for the sample mean is given by: $$ \bar{x} = \frac{\sum_{i=1}^{n} x_i}{n} $$ where: • $\sum_{i=1}^{n} x_i$ represents the sum of all individual data values. • $n$ represents the total number of data values in the sample. Step 3: Apply the formula to the given example. The example provides a sample of birth weights (in grams) and states that there are $n=20$ values. Although not all 20 values are fully visible in the image, the sum of these values is given as $\sum x_i = 63338$ grams. Substitute these values into the formula: $$ \bar{x} = \frac{63338}{20} $$ Step 4: Calculate the sample mean. $$ \bar{x} = 3166.9 $$ The sample mean of the birth weights is $\boxed{\text{3166.9 g}}$.
